Special Issue Information

Dear Colleagues,

The past two decades of intelligent learning systems have fundamentally evolved around the advancement in deep neural networks (DNNs). DNNs have become a go-to model for various problems, from basic image understanding to complex segmentation and predictive analysis using big data (BD). For example, deep convolutional neural networks (DCNNs) are the backbones of state-of-the-art object classification, object localization, computer-aided diagnosis (CADx), robotics, and autonomous vehicles. Given a large set of labeled data, DNNs’ data representation mechanism has repeatedly proven superior to conventional human-engineered features.

Despite their adoption in a wide range of applications across all the fields of natural science and engineering, they do not scale well on resource-limited conditions, such as scarcity of data and hardware support. Specifically, in the domains where collecting annotated data is very costly and time-consuming since it requires domain expertise. In some cases, due to security and privacy, gathering a large amount of information is not even feasible. Hence, beyond a successful training and testing of DNNs in a laboratory setting, most real-world deployment does not have the luxury of a high-performance computing platform. To overcome these shortcomings, there is a huge demand for research and development of optimized DNNs with the following considerations: quicker training and convergence (higher training speed), applicability for real-time environments (higher inference speed), ability to reach generalization from a small number of data samples (even weekly supervised and unsupervised strategies are considered), scalability across computational platforms (GPUs, CPUs, and embedded platforms). A proposed solution can focus on one or more of the above criteria.

We request research articles presenting novel algorithms and experimental studies on machine vision applications, and ideas (methods, tools, concepts, or even literature surveys) that will contribute to the advanced development of future deep learning models for resource-limited environments.

Image Classification in JPEG Compression Domain for Malaria Infection Detection

Digital images are usually stored in compressed format. However, image classification typically takes decompressed images as inputs rather than compressed images. Therefore, performing image classification directly in the compression domain will eliminate the need for decompression, thus increasing efficiency and decreasing costs. However, there has been very sparse work on image classification in the compression domain. In this paper, we studied the feasibility of classifying images in their JPEG compression domain. We analyzed the underlying mechanisms of JPEG as an example and conducted classification on data from different stages during the compression. The images we used were malaria-infected red blood cells and normal cells. The training data include multiple combinations of DCT coefficients, DC values in both decimal and binary forms, the “scan” segment in both binary and decimal form, and the variable length of the entire bitstream. The result shows that LSTM can successfully classify the image in its compressed form, with accuracies around 80%. If using only coded DC values, we can achieve accuracies higher than 90%. This indicates that images from different classes can still be well separated in their JPEG compressed format. Our simulations demonstrate that the proposed compression domain-processing method can reduce the input data, and eliminate the image decompression step, thereby achieving significant savings on memory and computation time.

Recent advances in object detection play a key role in various industrial applications. However, a fully convolutional one-stage detector (FCOS), a conventional object detection method, has low detection accuracy given the calculation cost. Thus, in this study, we propose a half-inverted stage FCOS (HISFCOS) with improved detection accuracy at a computational cost comparable to FCOS based on the proposed half inverted stage (HIS) block. First, FCOS has low detection accuracy owing to low-level information loss. Therefore, an HIS block that minimizes feature loss by extracting spatial and channel information in parallel is proposed. Second, detection accuracy was improved by reconstructing the feature pyramid on the basis of the proposed block and improving the low-level information. Lastly, the improved detection head structure reduced the computational cost and amount compared to the conventional method. Through experiments, the proposed method defined the optimal HISFCOS parameters and evaluated several datasets for fair comparison. The HISFCOS was trained and evaluated using the PASCAL VOC and MSCOCO2017 datasets. Additionally, the average precision (AP) was used as an evaluation index to quantitatively evaluate detection performance. As a result of the experiment, the parameters were increased by 0.5 M compared to the conventional method, but the detection accuracy was improved by 3.0 AP and 1.5 AP in the PASCAL VOC and MSCOCO datasets, respectively. in addition, an ablation study was conducted, and the results for the proposed block and detection head were analyzed.

Introduced in the late 1980s for generalization purposes, pruning has now become a staple for compressing deep neural networks. Despite many innovations in recent decades, pruning approaches still face core issues that hinder their performance or scalability. Drawing inspiration from early work in the field, and especially the use of weight decay to achieve sparsity, we introduce Selective Weight Decay (SWD), which carries out efficient, continuous pruning throughout training. Our approach, theoretically grounded on Lagrangian smoothing, is versatile and can be applied to multiple tasks, networks, and pruning structures. We show that SWD compares favorably to state-of-the-art approaches, in terms of performance-to-parameters ratio, on the CIFAR-10, Cora, and ImageNet ILSVRC2012 datasets. Full article
