The goal of super-resolution (SR) techniques is to enhance the resolution of low-resolution (LR) images. How to evaluate the performance of an SR algorithm seems to be forgotten when researchers keep producing algorithms. This paper presents a task-oriented method for evaluating SR techniques. Our method includes both objective and subjective measures and is designed from the viewpoint of how SR impacts...
Image segmentation is very essential and critical to image processing and pattern recognition. Watershed is the most popular one among all the proposed image segmentation algorithms, but it suffers from over-segmentation. To resolve the over-segmentation problem and obtain a concise region representation has been the focus of many researchers. There are many ways to reduce the over-segmentation. However,...
In order to improve the invisibility and the robustness of semi-fragile watermarking, the paper first brings up the idea which embedding watermark based on the attackspsila characteristic, brings forward the region segmentation operator and the double-step embedding method. The paper puts forward the characteristic and its representation in DWT transform domain based on visual features model, and...
Detecting and segmenting out the regions of interest (ROIs) is one of the foundations in image processing and analysis. Because the final information sink of images is human, for segmenting out the ROIs effectively, we need to study human visual system (HVS) and imitate the behaviors when human viewing a scene. Researchers have found several factors which affect human attentions by studying eye movements...
