histogram specification

基本解釋

Objective To employ an improved Exact Histogram Specification for contrast enhancement of medical ultrasonic images.
目的探求一種改進的精確直方圖規(guī)格化方法，提高醫(yī)學超聲圖像的對比度。
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技術，能有效地改善圖像的對比度和灰度動態(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.
在對比指紋圖像的灰度直方圖增強的技術的基礎上，針對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)則計算量大的情形，提出一種改進的規(guī)定化算法。
