Image enhancement is one of main contents of image processing, improving the intelligibility of the image, that is highlighting some features of the image selectively, make it more applicable to specific areas is the main objective of image enhancement. Breast cancer is one of tumor, the human tissue, illumination, noise and other factors make the

As atmospheric scattering of the fog, the contrast and color of the image taken infog conditions will be degraded, so the processing of the fog images is of greatsignificance. Current fog image processing include image enhancement and imagerestoration these two directions; image enhancement based on the perspective ofdigital images and enhance image contrast in order

This article is based on the agricultural insurance, research on the edge extraction technology of dairy cows’back image. When get cover for the dairy cows, we can gathering cows’images, then extract the images’feature, if the insured dairy cow was dead or ill, we can distinguish it from the others. Because of the biological characteristics of

With the rapid development of intelligence and automation, the traditional identification technology can not meet the demand for speed and accuracy more and more, on the contrary, modern biological recognition technology based on the information processing becomes a research hotspot. The automatic fingerprint identification has become one of the most extensive applications of biometrics because

In some current automatic fingerprint identification algorithms, there still exist severalproblems, such as, low orientation field accuracy, poor pre-processing effect, slow matching speed,poor recognition effect for low quality fingerprint images. In this paper, three new algorithms forthe fingerprint image pre-processing and the feature matching are proposed. To some extent, ouralgorithms not only enhance the speed
