here is the works using pysimgple gui create a widows & display image, using opencv to process image
Demo program that displays image using OpenCV and applies some very basic image functions
-- functions from top to bottom -
Gray: change image color to Gray
HSV: change image color to HSV
LUV: change image color to LUV
LAB: change image color to LAB
YUV: change image color to YUV
Cal_EQ: Image equalizeHist
threshold: simple b/w-threshold on the luma channel, slider sets the threshold value
canny: edge finding with canny, sliders set the two threshold values for the function => edge sensitivity
contour: contour finding in the frame, slider sets the value of threshold for b/w using threshold to find
Found objects are drawn with a red contour.
blur: simple Gaussian blur, slider sets the sigma, i.e. the amount of blur smear
