Real-time image processing techniques are used in many automation applications like in autonomous vehicle (AV) and robot control. In this paper, an image processing system for real-time video signal processing is studied, using DSK 6713 kit from Texas Instruments. The DSK kit is used to acquire frames from a camera module through HPI port and store them into external SDRAM memory. The DSP is used to extract the frames from memory through EMIF bus, and to run complex processing algorithms on 1D and 2D signals, like spectral analysis and artificial intelligence. Studying the system performances, three possible bottlenecks were identified and analyzed regarding image processing algorithms.

Copyright protection of digital images has become vital in the modern era where multimedia content is the dominant form of traffic in networked multimedia communication systems. Hence, there is a need for building technologies around robustness and computational efficiency for watermark embedding and extraction through state-of-the-art cryptographic algorithms. In this paper, we have proposed a blind image watermarking system that applies Henon chaotic map for watermark embedding and Elliptic Curve Cryptography (ECC) for securely sending the algorithmic parameters to the receiver. Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) are utilised for hybrid decomposition of the host image. The metrices used for the evaluation of the robustness and imperceptibility of this watermarking system are the Peak signal to Noise Ratio (PSNR) and Normalized Cross-Correlation (NC) and the Central processing Unit (CPU) runtime was recorded in order to assess the system's execution speed. © 2021 ieee.

Electroencephalography (EEG) signals can demonstrate the activities of the human brain and recognize different emotional states. Emotion recognition based on full EEG channels leads to the use of redundant data and increases the hardware complexity. This paper presents a channel selection method based on a new Binary Many-Objective Particle Swarm Optimization with Cooperative Agents (BMaOPSO-CA). More specifically, we perform unsupervised feature learning with recurrent convolutional layers based on autoencoder architecture directly from clean EEG signals. Extensive validation on three public effective benchmarks, i.e. DASPS, DEAP, and SEED which are different in channel number used stimuli, and participant ratings, was carried out with subject independent scheme. As result, the experimental study highlights the optimal electrode locations related to emotions, leading to analyze the relationship between specific brain regions and emotions.

Because of its practical uses in our daily lives, manuscript number identification is gradually relevant in the present times. Numerous identification techniques such as calligraphy number identification are deployed in many areas where great classification efficiency is required in recent years. In addition pattern recognition is a key component of any computer vision or artificial intelligence system. Machine Learning as well as Computer Vision researchers have used it extensively to build practical applications such as reading computerized bank draft numbers. In this project, we utilized an ANN to develop several surfaces attached development of a thinking computer system with two invisible surfaces to recognize manuscript numbers. The backpropagation method searches for the weight value that delivers the lowest overall error in the network while data processing between layers. Invisible layer neurons employ the ReLU activation function, whereas output neurons use SoftMax. The testing was done using the MNIST handwritten database, which is freely available. Finally retrieved a complete 60,000 digit pictures from the MNIST database for training, validation and testing.

This paper explores the problem of automated iris segmentation and pupil detection. The motivation to develop such a system is that an accurate detection of the eye, iris and pupil provides useful information for many applications from various domains, such as medicine, biometrics, and fashion industry. The paper features the following contributions: training of a fast eye landmarks detector, an original and precise algorithm for an estimating the center of the pupil and the iris margin, especially where the eyelashes cover it, and the manual annotation of a new benchmark dataset for testing purpose. The proposed method is proved to be very accurate: for all detected points, the error is smaller than an approximation of the diameter of the pupil.

Landmark localization of facial soft tissue (FST) is a basic step in 3D morphometric analysis of human face. However, there are few studies on landmark localization of 3D scan images based on deep learning. The methods based on 2D images cannot be directly applied due to the non-Euclidean data structure. In this paper, we propose an end-to-end learning framework to automatically localize 28 landmarks on 3dMD scans, called FST-Net. Our method extracts features from texture images and mesh models. New texture mappings for 3dMD scans are generated by projection to fuse texture and structure features. A dual-branch network integrating transformers is applied to predict the landmark heatmaps from coarse to fine. A local coordinate regression module based on probabilistic distance and heatmap predictions is proposed to compute the landmark coordinates. We collect and annotate 297 3dMD face scans from the clinic to evaluate our model. Experiments show that the average localization error of the model is 1.204mm (the clinically acceptable precision range is 1.5 mm), and the correct landmark detection rate equals to 70.89%. Our model outperforms the current state-of-the-art deep learning methods for landmark localization on the mesh model.

The networked devices over the IoT environments have accumulated a large volume of data, and therefore it becomes challenging for many typical surveillance applications to handle and analyze these massive real-time data. In this paper, we propose a multi-target approach to real-time object detection for surveillance applications that can be used as an edge service for handling and analyzing the real-time massive data acquired by a huge number of terminal devices. A lightweight multi-layered Convolutional Neural Network based on Darnet-53 structure is adopted to learn the multi-target features in training dataset for classifying and detecting image objects in unseen image instances, which is. A pre-processing approach including image screening, image enhancement and manual category annotation is presented for building the training dataset of surveillance applications. At last, extensive experiments were made to validate the effectiveness and efficiency of handling and analyzing the real-time massive data based on the proposed approach.

Reversible data hiding is a data hiding process in which data is encrypted into an image as a means of authentication, and hidden data is used to hide the original image, and RDH is often used in areas where data authenticity and data preservation are important, such as legal/criminal investigations, medical images. In this study, this paper designed a novel reversible data hiding system that utilizes the Steghide algorithm to encrypt images and hide data, as well as an artificial neural network to recover embedded text and structure. Based on the analysis of the test results, it was concluded that the RDH scheme proposed in this article has the same or higher system accuracy and reliability as the existing RDH scheme. To further refine the system results in future studies, this paper proposes to increase the number of training iterations and the number of images in the training dataset to further improve the accuracy and reliability of the development.

To overcome the data movement bottleneck, near-sensor and in-sensor computing are becoming more and more popular. However, in the existing near-/in-sensor computing architectures for vision tasks, the effect of the image signal processing (ISP) pipeline, which is of great importance to the final vision performance [1], is always ignored. In this work, we propose a synthesized RAW image-based end-to-end computer vision paradigm, taking the effect of ISP pipeline into account. In the proposed approach, a generative adversarial network (GAN)-based tool is used to convert the fully processed color images to their corresponding RAW Bayer versions, generating the training data for end-to-end vision models. In the inference stage, RAW images from the sensor are directly fed to the end-to-end model, bypassing the entire ISP pipeline. Experimental results show that by training/tuning the CNN models using synthesized RAW images, it is possible to design an end-to-end (from RAW image to vision task) vision system that directly consumes RAW image data from the sensor with negligible vision performance degradation. By skipping the ISP pipeline, an image sensor can be directly integrated with the back-end vision processor without a complex image processor in the middle, making near-/in-sensor computing a practical approach.

Early detection and diagnosis of brain tumors are crucial for improving patient outcomes. While convolutional neural networks (CNNs) have demonstrated promise in detecting tumors from magnetic resonance images (MRI), traditional meth-ods often suffer from overparameterization, resulting in lower accuracy improvements despite higher computational demands. To address this, we propose an efficient approach, Fuzzy Atrous Convolution (FAC), with two additional modules: Top of the funnel and middle of the funnel. In this approach, fewer trainable parameters are required while maintaining high classification accuracy. A novel convolutional operator is introduced in the FAC model that dilates the receptive field while preserving input data, enabling efficient feature map reduction and accurate tumor detection. In the propose model, fuzzy logic improves adaptability and robustness. Experiments on three datasets confirmed the efficiency of proposed approach (FAC) and it achieved accuracies of 98.83%, 99.67%, and 99.56% on Datasets I, II, and III, respectively. Compared with large transfer learning models, Proposed approach has over 300 times fewer parameters, making them efficient for early brain tumor detection.
