histogram specification

基本解釋

Objective To employ an improved Exact Histogram Specification for contrast enhancement of medical ultrasonic images.
目的探求一種改進(jìn)的精確直方圖規(guī)格化方法，提高醫(yī)學(xué)超聲圖像的對(duì)比度。
The image enchancement based on histogram equalization and specification can improve the contrast details and the dynamic range of gray level of the image.
基于直方圖均衡化和規(guī)定化處理的圖像增強(qiáng)技術(shù)，能有效地改善圖像的對(duì)比度和灰度動(dòng)態(tài)范圍。
Histogram specification can change the histogram of image into an specific form, and it can enhance the image of one gray range , so as to give the information that users interested in.
在對(duì)比指紋圖像的灰度直方圖增強(qiáng)的技術(shù)的基礎(chǔ)上，針對(duì)均衡化算法的不足和現(xiàn)有直方圖規(guī)定化算法中映射規(guī)則計(jì)算量大的情形，提出一種改進(jìn)的規(guī)定化算法。
