2018-09-03 07:19:15 -0600 | marked best answer | strange result of transformation of frame of VideoCapture I have a code and function test() I expected that this function will return a transformed frame, totally white. But instead, it returns me a frame where 1/3 of columns white: if I transform code above instead of I got this: and if I change code like this: I eventually got that I expected, white frame. Why it works so weird? I have a loop on all rows and columns and yet I don't get totally white picture. If I use this function test() on usual picture, it returns white Mat. But with frame of VideoCapture result is different. Why? |
