Near-infrared hyperspectral imaging (NIR-HSI) integrated with expert systems can support the monitoring of active pharmaceutical ingredients (APIs) and provide effective quality control of tablet formulations. However, existing quality control methods usually test a limited number of variability sources affecting the final product. This study examines the potential of NIR-HSI (in the spectral range of 935.61-1720.2 nm) as an advanced and high-throughput detector to identify different manufacturing factors and their fluctuations that impact tablet properties. These are, for instance, particle sizes of powdered excipients, their mixing, compression force used to form a tablet, origin of ingredients, storage conditions, and concentration of API. During the study, the novel expert system approach was developed to support NIR-HSI, enabling the detection of subtle, diverse substandard anomalies in tablets. The system combines (i) hyperspectrograms, which characterize and simplify tablet spatial heterogeneity through principal component analysis scores distribution, and (ii) a one-class classifier (OCC), trained exclusively on target class samples, without the need for substandard tablets. The system was trained to recognize known sources of variation and validated using tablets with cellulose, magnesium stearate, and ascorbic acid as API. It outperformed the alternative approach based on averaged spectra, achieving 100.00% sensitivity and 98.77% specificity.

The improvement in existing remote sensing detectors often relies on complex structures and deeper convolutional layers, leading to a significant increase in computational complexity. While previous works have designed various novel lightweight convolutions to improve target feature representation, these structures often overlook the unique prior knowledge of remote sensing scenes when applied to aerial detection tasks, resulting in decreased detection performance. Specifically, this prior knowledge includes: (1) Accurate detection of aerial objects often requires extensive contextual information. (2) The range of contextual information needed for different categories varies greatly. To address this, our paper fully considers this prior knowledge and proposes the Adaptive Spatial Selection Kernel Network (ASSK-Net). We first use large kernel convolution decomposition operations to decouple a series of convolutions with smaller sizes and rapidly expanding dilation rates, constructing diverse receptive fields with different spatial coverage ranges while significantly reducing computation. Based on this, a spatial selection mechanism is used to effectively weight feature maps with different levels of information richness, enhancing the feature differences between targets and backgrounds. Finally, we design an adaptive class equilibrium loss function, increasing the loss weight with rare categories and other easily confused categories with similar classification scores, thus improving the discriminative capability for rare categories. Comprehensive experiments on datasets (such as DOTA, UCAS-AOD, and HRSC2016) indicate that our ASSK-Net achieves optimal performance, effectively balancing computational complexity and detection accuracy.

In response to the traditional detection methods of not detecting the target, not seeing it, blurring the outline and details of the image, etc., using a combination of infrared and polarization detection, the infrared image information and the polarization image information are decoded to solve the problem of not being detected or seen in various environments. For the target local feature extraction process of large amounts of data, slow extraction speed, and other problems, an improved SIFT algorithm for local feature extraction of polarized images with deep learning is proposed. Experimental results show that the modified algorithm combines the advantages of polarimetric imaging and deep learning to achieve fast feature extraction of targets in simple or complex backgrounds. The algorithm improves the speed of local feature extraction of polarized images by 3.6% and the accuracy of extraction by 2.8%. The algorithm provides the theoretical basis for target classification, identification, and tracking techniques. © 2023 SPIE. All rights reserved.

Facial target detection is an important task in computer vision. Because heterogeneous face detection shows broad prospects, it has attracted extensive attention from the academic community. In recent years, with the rise of deep learning and its applications in computer vision, face detection technology has made great strides. This paper uses multi-task cascaded convolutional neural network (MTCNN) for heterogeneous face feature detection. This algorithm makes full use of the advantages of image pyramid, boundary regression, fully convolutional attention networks and non-maximum suppression. The main idea of this paper is to use candidate frame plus classifier for fast and efficient face detection. Specifically, the candidate window is generated by the proposal network (P-Net), and the high-precision candidate window is filtered and selected by the reduced network (R-Net), and the final bounding box and facial key points are generated by the output network (O-Net). In order to prove the effectiveness of this method in visible light, near-infrared and sketch face recognition scenes, it was verified in the datasets of CUFS, CUFSF and CASIA NIR-VIS 2.0. Experiments show that this method is effective for face images in heterogeneous face and is better than the latest algorithms.

infrared target detection is the key technology of infrared search and tracking system. In the case of complex background, dim target detection face difficulties such as high algorithm complexity and low robustness. To solve these problems, an infrared dim target detection method via handcrafted features and deep information combination is proposed. Firstly, an adaptive Top-Hat segmentation is used to extract candidate target region, then 128-dimensional deep learning features and 106-dimensional hand-crafted features are calculated for candidate region respectively. Finally, features are concatenated and input into a 4-layer fully connected network for feature fusion and classification to exclude false alarm sources. Experiments show that the proposed method can detect infrared dim targets accurately and robustly in various scenes.

With the continuous enhancement of remote sensing technology, using satellite to detect and identify targets has important research significance in military and civil fields. Due to the influence of many interference factors, the background of large-scale infrared remote sensing images is often complex and the target intensity is weak, and efficient and accurate target detection has become a difficult issue. Therefore, the purpose of this paper is to solve the issues of inaccurate target detection and inefficient hardware deployment. Firstly, the rough detection method based on the grey variance and gradient features can effectively extracted the target candidate region and eliminate simple background interference. Secondly, the fine detection method based on multiple features is used for ship classification, in which structured LBP (local binary pattern) features is applied to calculate the structured feature histogram, screen the local target features, and calculate and classify the global features through two-dimensional Fourier features. Thirdly, the improved non-maximum suppression method is used to merge adjacent target points to ensure the accuracy of the algorithm to the greatest extent. Finally, an efficient feature computing unit and multichannel storage structure is proposed to optimize the FPGA (field-programmable gate array) implementation and relieve the pressure of high data rate processing and can eliminate a lot of computational redundancy. Experimental results validate that, compared with some advanced methods, our method can reduce the processing time by up to 1.71 times while the ship detection performance can be improved by up to 5.4%. Furthermore, the hardware processing capability was verified by three indicators, among which the traversal processing performance and throughput can increase by up to 1.7 and 6.7%, while the delays of key modules can decrease by up to 4%.

To date, careful data treatment workflows and statistical detectors are used to perform hyperspectral image (HSI) detection of any gas contained in a spectral library which is often expanded with physics-models to incorporate different spectral characteristics. Generally, surrounding evidence or known gas-release parameters are used to provide confidence in or confirm detection capability, respectively. This makes quantifying detection performance difficult as it is nearly impossible to develop absolute ground truth for gas target pixel presence in collected HSI. Consequently, developing and comparing new detection methods, especially machine learning (ML) based methods, is beholden to subjectivity in derived detection map quality. In this work, we demonstrate the first use of transformer-based paired neural networks (PNNs) for one-shot gas target detection for multiple gases while providing quantitative classification and detection metrics for their use on labeled data. Terabytes of training data are generated from a database of longwave infrared (LWIR) HSI obtained from historical Mako sensor campaigns over Los Angles. By incorporating labels, singular signature representations, and a model development pipeline, we can tune & select PNNs to detect multiple gas targets which are not seen in training on a quantitative basis. We additionally assess our test set detections using interpretability techniques widely employed for ML-based predictors, but less common on detection methods relying on learned latent spaces. © 2024 SPIE.
