Architecture for Image Contrast Enhancement Applications by Altera Quartus II

摘要

Objectives: To design the hardware architecture for contrast enhancement applications. Methods / Statistical Analysis: Image improvement is the technique utilized to make strides the visible illustration of an image. Histogram equalization is one of the most vital techniques of image improvement. Findings: The fundamental idea of histogram equalization is to re-map the gray degrees of the image. Indeed in spite of the fact that these approaches may improve the differentiate of a picture in a successful and proficient way, they ordinarily have a few downsides, like misfortune in data, commotion enhancement and over enhancement. In this extend a modern strategy which performs differentiate improvement may named as adjusted color protecting versatile gamma adjustment. The upgrade is gotten by a combination of altered histogram and its versatile gamma adjustment. Applications / Imporovement:The proposed strategy is analyzed for many differentiate test pictures. It works better than existing. In addition to that the VLSI architecture of the algorithm is developed for size 2×2 image using ALTERA QUARTUS II. The same architecture can be extended to entire image.
