Special Issue Information

Dear Colleagues,

Object detection and segmentation using on sensing technology refers to the use of advanced sensing techniques and algorithms to identify and segment objects or entities in a given environment.

It involves the development and implementation of computer vision systems that can automatically detect, track, and segmentation specific objects or patterns in real time. Sensing technology plays a crucial role in object detection and segmentation by capturing and processing data using various technologies, such as cameras, medical imaging devices (CT, MRI, and ultrasound imaging), LiDAR (Light Detection and Ranging), radar, or thermal sensors.

These sensors enable the acquisition of visual or non-visual data, which are then analyzed using intelligent algorithms to identify and segment objects based on their characteristics, such as shape, color, size, or motion. Object detection and segmentation systems have numerous applications across various industries. In the field of autonomous vehicles, these technologies detect and track pedestrians, other vehicles, and road signs to ensure safe navigation. In surveillance and security, object detection and recognition help identify suspicious activities or intrusions in real time. In the field of medical image processing, these techniques accurately detect and segment lesion areas. They are also used in industrial automation to monitor and control manufacturing processes, track inventory, or ensure workplace safety.

The processes of object detection and segmentation typically involve multiple stages, including image or data acquisition, preprocessing, feature extraction, classification, and post-processing. During feature extraction, algorithms identify specific patterns or characteristics that distinguish the objects of interest from the background or other objects. Classification algorithms then use these features to categorize objects into predefined classes or categories. The development of object detection and segmentation systems based on sensing technology relies on continuous hardware and software advancements. These technologies hold great potential for enhancing efficiency, safety, and automation in various domains by performing accurate and reliable detection and segmentation.

We welcome both original research papers and review articles that showcase the significant developments in these fields. Potential areas of interest include, but are not limited to, the following:

Small intestinal stromal tumor (SIST) is a common gastrointestinal tumor. Currently, SIST diagnosis relies on clinical radiologists reviewing CT images from medical imaging sensors. However, this method is inefficient and greatly affected by subjective factors. The automatic detection method for stromal tumors based on computer vision technology can better solve these problems. However, in CT images, SIST have different shapes and sizes, blurred edge texture, and little difference from surrounding normal tissues, which to a large extent challenges the use of computer vision technology for the automatic detection of stromal tumors. Furthermore, there are the following issues in the research on the detection and recognition of SIST. After analyzing mainstream target detection models on SIST data, it was discovered that there is an imbalance in the features at different levels during the feature fusion stage of the network model. Therefore, this paper proposes an algorithm, based on the attention balance feature pyramid (ABFP), for detecting SIST with unbalanced feature fusion in the target detection model. By combining weighted multi-level feature maps from the backbone network, the algorithm creates a balanced semantic feature map. Spatial attention and channel attention modules are then introduced to enhance this map. In the feature fusion stage, the algorithm scales the enhanced balanced semantic feature map to the size of each level feature map and enhances the original feature information with the original feature map, effectively addressing the imbalance between deep and shallow features. Consequently, the SIST detection model’s detection performance is significantly improved, and the method is highly versatile. Experimental results show that the ABFP method can enhance traditional target detection methods, and is compatible with various models and feature fusion strategies. Full article
