Recent advancements in artificial intelligence algorithms for medical imaging show significant potential in automating the detection of lung infections from chest radiograph scans. However, current approaches often focus solely on either 2-D or 3-D scans, failing to leverage the combined advantages of both modalities. Moreover, conventional slice-based methods place a manual burden on radiologists for slice selection. To overcome these challenges, we propose the Recurrent 3-D Multi-level Vision Transformer (R3DM-ViT) model, capable of handling multimodal data to enhance diagnostic accuracy. Our quantitative evaluations demonstrate that R3DM-ViT surpasses existing methods, achieving an impressive accuracy of 96.67%, F1-score of 96.88%, mean average precision of 96.75%, and mean average recall of 97.02%. This research signifies a significant stride forward in the automated detection of lung infections through multimodal imaging.

Dense depth estimation in endoscopic images can provide surgeons with important information for performing accurate minimally invasive surgeries. However, it is difficult to estimate the absolute depth of the scene based on monocular endoscope. Depth values in endoscopic images change drastically during the operation, which make it hard to estimate them with a fixed baseline. In this paper, we propose a depth estimation scheme with multiple baselines. The monocular endoscope is moved horizontally by a robotic endoscope holder to generate stereo images. A pixel-level depth map fusion algorithm is designed to combine depth values estimated with different baselines. Experimental results show that the proposed method improves the accuracy of depth estimation and the visual quality of depth maps.

Entropy modeling plays an important role in estimating the rates of latent representations and optimizing the rate-distortion performance for learned image compression. Autoregression modules are demonstrated to eliminate spatial/channel-wise redundancy of latent representations in fixed-rate learned image compression. However, it cannot be efficiently achieved in progressive coding due to the high computational complexity raised by element-wise probability prediction. In this paper, we propose a learned progressive image compression method that enables spatial autoregression for entropy modeling. Specifically, we develop a novel codeword alignment scheme to prevent coding redundancy and achieve efficient autoregression of latent representations in different quality layers. Consequently, conditional probability estimation for the latent prediction can be achieved based on spatial autoregression in a layer-wise manner. We further extend the proposed method by dead-zone quantizers to obtain promoted rate-distortion performance. The proposed method is a successful attempt to enable spatial autoregression in learned progressive coding and further bridge the performance gap with fixed-rate models. Experimental results show that it outperforms traditional methods such as JPEG and BPG, as well as recent fine-grained learned progressive coding models DPICT and PLONQ in terms of rate-distortion performance. © 2023 ieee.

image sentiment analysis is a domain fraught with the dual challenges of interpreting complex visual content and discerning the subtle emotional undertones it may convey. Despite the notable successes of existing visual language pretraining (VLP) models in a variety of visual tasks, they fall short in the nuanced realm of sentiment analysis. This shortfall is primarily due to their inadequate processing of sentiment-specific cues-most notably, the oversight of localized sentioment cues within images and the intricate interplay of these signals. Furthermore, these models inadequately harness the rich sentiment cues often embedded in accompanying text. In response to these shortcomings, we introduce the Specific Sentiment Mask Auto-encoder (S2MA) model, which is expressly designed to integrate sentiment information during the pretraining process. S2MA is meticulously engineered to focuse on both intermodal and intramodal sentiment cue, thereby augmenting the model's proficiency in anlysising the sentiment knowledge within visual content. Rigorous comparative evaluations of S2MA against the CLIP model, across a spectrum of downstream datasets in zero-shot and supervised learning scenarios, have validated the superiority of our approach. The empirical outcomes affirm S2MA's capacity to significantly enhance the analytical landscape of image sentiment analysis.

With advancements in computer and communication technologies, the production, utilization and applications of digital images is at an unprecedented rate. Recent applications include military communications, remote sensing, novel engineering designs storage and communications, as well as medical imaging. In most cases, such images convey highly sensitive or confidential information, which creates a strong need for the design of secure and robust color image cryptosystems. Recent literature has shown that fractional-order functions exhibit improved performance over their corresponding integer-order versions. This is especially true in their use in image processing applications. In this research work, we make use of a four-dimensional (4D) hyperchaotic Chen map of fractional-order, in conjunction with a sine chaotic map and a novel hybrid DNA coding algorithm. A thorough numerical analysis is presented, showcasing the security performance and efficiency of the proposed color image cryptosystem. Performance is gauged in terms of resilience against visual, histogram, statistical, entropy, differential, as well as brute-force attacks. Mean values of the metrics computed are as follows. MSE of 9396, PSNR of 8.27 dB, information entropy of 7.997, adjacent pixel correlation coefficient of 0, NPCR of 99.62%, UACI of 33, MAE of 80.57, and a very large key space of 2(744). The proposed image cryptosystem exhibits low computational complexity, as it encrypts images at a rate of 4.369 Mbps. Furthermore, it passes the NIST SP 800 suite of tests successfully. Comparison of the computed metrics of the proposed image cryptosystem against those reported in the state-of-the-art by counterpart algorithms show that the proposed cryptosystem exhibits comparable or superior values.

Medical images often incorporate doctor-added markers that can hinder AI-based diagnosis. This issue highlights the need of inpainting techniques to restore the corrupted visual contents. However, existing methods require manual mask annotation as input, limiting the application scenarios. In this paper, we propose a novel blind inpainting method that automatically reconstructs visual contents within the corrupted regions without mask input as guidance. Our model includes a blind reconstruction network and an object-aware discriminator for adversarial training. The reconstruction network contains two branches that predict corrupted regions in images and simultaneously restore the missing visual contents. Leveraging the potent recognition capability of a dense object detector, the object-aware discriminator ensures markers undetectable after inpainting. Thus, the restored images closely resemble the clean ones. We evaluate our method on three datasets of various medical imaging modalities, confirming better performance over other state-of-the-art methods.

Inspection of aircraft skin is required as per the Corrosion Prevention and Control Program (CPCP) to ensure aircraft structural integrity. Human visual inspection is the most widely used technique in aircraft surface inspection, according to the CPCP. Scheduled inspections and regular maintenance of an aircraft through conventional methods constitute tedious and lengthy procedures. Often the visual inspections lead to subjective judgement and do not constitute repeatability. Many automated vision-based aircraft skin inspection systems have been designed to provide a safe, quick, and accurate visual assessment over the past years. This paper presents a section of research investigating defect detecting and accurately locating the outer body of an aircraft using an Unmanned Aerial Vehicle (UAV) to capture images and digital image processing techniques to locate possible cracks. The inspection system is used to initially detect locations of cracks (defects) on an aircraft's outer skin and the detected crack is further investigated using thermal and ultrasound imaging methods. The scope of this paper includes a review of the design and development of a series of advanced dedicated image processing algorithms suitable for applying digital image processing on images captured from the outer surface of a typical aircraft fuselage. © 2023 ieee.

image caption generation has witnessed significant advancements with the integration of Deep Learning (DL) models. By leveraging DL techniques such as InceptionResNetV2 for feature extraction and transformer-based architectures for natural language processing, achieves remarkable results in generating descriptive captions for images. Unlike traditional Recurrent Neural Network approaches, which suffer from issues like vanishing gradients and lack of parallelization, this method offers improved efficiency and scalability. The synergy between DL models and Natural Language Models enables the system to capture intricate sematic relationships between visual content and textual descriptions, resulting in more accurate and contextually relevant captions. By integrating InceptionResNetV2 and Detection Transformer, this approach leverages the strengths of both architectures, achieving state-of-the-art performance in object detection tasks. Through joint training, the model learns to detecting images and labelling/captioning on up to 50% occluded images with Precision of 0.982, Recall of 0.931, F1 Score of 0.942 and Sensitivity of 0.892.)

In image stitching, artifacts caused by misalignment affect the visual quality and the performance of subsequent tasks such as segmentation and detection. This paper proposes SMPR, a reconstruction-based aligned image composition method to minimize artifacts. SMPR fuses images in part of the overlapping areas and reconstructs other portions from single images. Specifically, we propose a seam mask generation method to obtain optimal seam masks that pass through minimal misalignment. During training, we use the seam masks to guide the model in detecting optimal fusion areas. In testing, the model can detect fusion areas without seam masks and reconstruct stitching results. We propose a quantum-inspired local aggregation (QILA) module to improve feature reconstruction performance. We develop an encoder-decoder network with QILA and experiment on a real-world dataset. The experiments show that our method outperforms state-of-the-art methods in both qualitative and quantitative aspects.

Due to relying on accurate estimates of the atmospheric scattering parameters for atmospheric scattering models(ASM), existing haze removal methods suffer from some drawbacks, such as imbalanced contrast and missing details. To address the above issues, this paper proposes a two-stage dehazing network called CEDhazeNet. It consists of a contrast enhancement module (CE) and a texture detail restoration module (TDR). In CE, we introduce a novel curve enhancement dehazing model to tackle the problem of contrast imbalance. Specifically, we observe that inverting the hazy image can accentuate all the regions obscured by haze, and by enhancing the exposure of the inverted image, we can significantly reduce the impact of haze on image contrast. In TDR, we construct a multi-scale information distillation network, which use more effective information, such as edges and spots to recover the texture details of hazy image. Extensive experiments on both synthetic and real world hazy image datasets demonstrate that CEDhazeNet outperforms state-of-the-art haze removal methods in terms of quantitative accuracy and subjective visual quality.
