An image overall complexity evaluation method based on LSD line detection

Document Image Dewarping Based on Text Line Detection and Surface Modeling (RESEARCH NOTE)

Document images produced by scanner or digital camera, usually suffer from geometric and photometric distortions. Both of them deteriorate the performance of OCR systems. In this paper, we present a novel method to compensate for undesirable geometric distortions aiming to improve OCR results. Our methodology is based on finding text lines by dynamic local connectivity map and then applying a l...

An Image Splicing Detection Method Based on PCA Minimum Eigenvalues

This paper presents a novel and effective image splicing forgery detection method based on the inconsistency of irrelevant components between the original and the tampered regions. The specific irrelevant components can be described by the minimum eigenvalues obtained by the principal component analysis (PCA) without knowing any prior information. To avoid the impact of local structures, a pixe...

An Automatic Method for Image Matting Based on Saliency Detection ⋆

Image matting aims at extracting foreground from a given image by means of color and alpha estimation. An automatic matting method based on saliency detection was proposed in this paper, which takes the advantages of saliency detection as prior information instead of user interaction. After getting the saliency map, a cost function was constructed to obtain an alpha matte. Moreover, with the in...

Cross-Efficiency Evaluation Based on an Interval Method

Tongue image constitution recognition based on Complexity Perception method

Background and Object: In China, body constitution is highly related to physiological and pathological functions of human body and determines the tendency of the disease, which is of great importance for treatment in clinical medicine. Tongue diagnosis, as a key part of Traditional Chinese Medicine inspection, is an important way to recognize the type of constitution.In order to deploy tongue i...
