Image enhancement is one of the important tasks in image pre-processing to improve the image quality for other applies. The traditional morphological enhancement operator cannot well address enhancement process for low illumination color image. In this paper, we present a new morphological operator based on graphic theory for the enhancement of low illumination color image. Firstly, the notable Weber's...
In image stitching, well performed stitching result is hard to achieve for images with large difference of contrast. This paper proposes a method based on histogram equalization by enhancing the contrast of stitching images. On the basis of image enhancement this method uses the algorithm of SURF (Speeded Up Robust Feature) feature points, K-Nearest Neighbor and bilateral matching method to match...
In the process of layout optimization, it is needed to deal with nets through the image of CIF layout. But there has not any tool to extract image layout from CIF layout. According to actual integrated circuit (IC) layout characteristics, this paper proposes a new algorithm to extract image layout from CIF layout based on sliding window. With the sliding window, new algorithm solves the problem of...
