Compressing an image with more bits automatically allocated to the region of interest (ROI) than to the background can both protect key information and reduce substantial redundancy. This paper models ROI image compression as an optimization problem of minimizing a weighted sum of the rate of the...

The envelope image before log compression to adjust the wide dynamic range, is an intermediate image that represents the echogenicity of the scanned region by taking only the magnitude of the received RF signals (i.e., ignoring phase information). Using this envelope image, two meaningful ...
The performance of the network can be optimized by adopting the strategy of training the segmentation task first and using the deep supervision training method. At length, the advantages of object detection and semantic segmentation are tactfully combined. Our model achieves mIOU 79.37% and mAP@0.5...
