1. Obtain and set pixels
First determine whether the point is in the image. If it is in the image, use this formula to calculate the pixel. The
pixel is stored in the data type of float data, and float v can be assigned to data.
2. Copy the image
First make an image of the same size, <code has been given>
and then traverse all points of the original image, assign its pixel value to the same position of the new image
3. Grayscale image
Traverse all points, convert RGB pixel values to R \ G \ B, and then use the weighted average to calculate the grayscale pixel K
K = 0.299R + 0.587G + 0.114B
4. Change the color of the image. The
pixel value of the c channel is B in rgb to
traverse all points in the image, and then add the new pixel (that is, the parameter v) to the c channel.
5. Fixed image value (not sure about ww
Make sure the pixel value in the image is between 0 and 1. Clamp the image, if it is less than 0, it will be set to 0, if it is greater than 1, it will be set to 1.
6 & 7, RGB <----> HSV HSV super detailed
Hue (H), Saturation (S), Brightness (V)
