halcon-直方圖均衡

****對影像進行線性灰度變換*******
 
dev_clear_window ()

read_image (Image, 'C:/Users/Public/Documents/MVTec/HALCON-18.11-Steady/examples/images/lcd/tft_cells_01.png')
get_image_size (Image, Width, Height)
 
dev_open_window (0, 0, Width, Height, 'black', WindowHandle)

*灰度轉化
rgb1_to_gray (Image, GrayImage)
GrayImage_1:= GrayImage
 
***********************************************************************
*計算影像的灰度值分佈
gray_histo (GrayImage, GrayImage, AbsoluteHisto, RelativeHisto)
*獲得灰度直方圖
gen_region_histo (Region, AbsoluteHisto, 255, 255, 1)

************************************************************************
*直方圖均衡化
equ_histo_image (GrayImage_1, ImageEquHisto)
gray_histo (Region, ImageEquHisto, AbsoluteHisto1, RelativeHisto1)
*獲得灰度直方圖
gen_region_histo (Region1, AbsoluteHisto1, 255, 255, 1)
