The capsule endoscopy images have the characteristics such as low resolution and low contrast, which cause some difficulties to analysis and diagnosis for the physicians, especially to computer aided diagnosis. To overcome these shortcomings, we propose a contrast-based forward and backward anisotropic diffusion method to enhance the capsule endoscopy images. Based on the local analysis of the capsule endoscopy images, we put forward a new concept of contrast. Then, we employ the forward and backward anisotropic diffusion to enhance the capsule endoscopy images. Experimental results show that this new method can efficiently enhance the capsule endoscopy images, which provides a better visualization and an improved discrimination of region of interest from the background. <\/jats:p>","DOI":"10.1142\/s0219878907001228","type":"journal-article","created":{"date-parts":[[2007,10,22]],"date-time":"2007-10-22T05:28:36Z","timestamp":1193030916000},"page":"117-126","source":"Crossref","is-referenced-by-count":2,"title":["A NOVEL ENHANCEMENT METHOD FOR CAPSULE ENDOSCOPY IMAGES"],"prefix":"10.1142","volume":"04","author":[{"given":"BAOPU","family":"LI","sequence":"first","affiliation":[{"name":"Department of Electronic Engineering, The Chinese University of Hong Kong, Shatin, N.T., Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MAX Q.-H.","family":"MENG","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, The Chinese University of Hong Kong, Shatin, N.T., Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2006.888338"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2006.881927"},{"key":"rf3","first-page":"63","volume":"26","author":"Bao Y.","journal-title":"IEEE Transactions on PAMI"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1109\/83.661192"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1109\/83.661185"},{"key":"rf7","doi-asserted-by":"publisher","DOI":"10.1109\/42.141646"},{"key":"rf8","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2002.800883"},{"key":"rf9","doi-asserted-by":"publisher","DOI":"10.1016\/j.compmedimag.2004.12.003"},{"key":"rf10","first-page":"1394","volume":"10","author":"Ge Z.
