WebOpen CV rect () Is an inbuilt function which is present in the open CV Public Library. this function is designed in order to provide for drawing of a rectangular shape given in an image to project that rectangle on the screen. this rectangular shape should essentially contain for sides, two sides parallel to each other and should be at an angle … Web19 de set. de 2016 · If you do a bitwise_and on these, you may notice not a single bit overlaps. So the result is 0. If you do a bitwise_or, you get 250. That's because with no overlap, it's the same as addition. 130 OR 131 is 131, because only the 1 bit is different.
