MATLAB: What does imsize = width * height means

#imagesize #height #width #dimension

Does it mean the image size can be obtained by multiplying the height and width? Will it get a matrix and/or a 2D image?

Since the matlab line above this is [height,width,~] = size(im); And the ~ variable means the dimensions of an image. Correct me if I am wrong. Thanks!

imsize = width * height would get you a scalar telling you how many elements there are in a 2D subset of the im array. It will not in itself generate a matrix -- just calculate the memory requirements for a matrix.

MATLAB: Horizontal and vertical projection of an image

The question is not clear. Perhaps this helps:

img = rand(100, 100) < 0.1;
h_projection = any(img, 2);
v_projection = any(img, 1);
cat_projection = cat(1, h_projection, v_projection(:));

Using SUM instead of ANY might be an option also.

MATLAB: Color HS histograms horizontal and vertical split

I don't know what "vertical split" means. What is an HS histogram? You can use hist() to get histograms for each color channel, for H, for S, and for V. What are the subimages? How did you get subimages?
