PROBLEM TO BE SOLVED: To conduct gamma correction of a printer on a monitor screen without using a measuring instrument. SOLUTION: An image display system 7 allows an output device 4 to print out data 3 of a test image and allows a display device 1 to display the data 3 on a monitor....

不同采集设备获取的图像像素差异非常大,并且用户采集图像时所处的环境并不固定,因此用户舌象图片的光照强度很有可能不能达到中e诊舌象数据库中舌象图片统一的光照强度。若是如此,用户进行舌象诊断的结果准确性将会大打折扣。因此,在舌象诊断前进行亮度自动调节是非常有必要的。 2 实现细节 本小组利用伽马校正(Gamma C...
Let’s test that theory. Here’s an image I made using Eric’s gamma grayator utility, enlarged using both methods:OriginalCorrect gammaIncorrect gammaIn this case it’s clear that the “correct” image really is the correct one. The incorrect one is too dull and gray. So, unfortunately,...
