Question

True or false

1) In morphological processing, structuring elements can be any size and have any shape
2) Erosion set pixel value to one when the structuring element hits the image.
3) Skeletonization is a morphological operation that deletes black foreground pixels
iteratively layer by layer until one-pixel width skeleton is obtained
4) To detect bright points or spike pixels in an image, convolution with a kernel filled with ones
is used.
5) The negative of an image with gray levels in the range [0, L-1] is obtained by using the
negative transformation, which is given by the expression: s=L-1-r.
