Hello, I am working on Image processing.Being new to this field , I don't know the concept of horizontal and vertical projection on an image. Can anyone please give a clear picture of projection in image processing as it would be very helpful for me to proceed forward.
Thanks in advance

Do you mean just summing the image vertically and horizontally?
verticalProfile = sum(grayImage, 2);
horizontalProfile = sum(grayImage, 1);

Thank you for your response ,RP(ring projection)and CP(central projection) are
methods for transforming 2-D pattern in to 1-D pattern , RP reduces the
dimensionality by performing projection along circles with different radius
, while CP reduces the dimensionality by performing projection
along lines with different polar angles.
