Image preprocessing

Because of image processing science widespreading, Image preprocessing of this branch of science also has a variety of sections where some of them are:

Edge detection

The most important part of an image, which contains the general information, is the edges of the areas where the change of color or intensity is at once sharp.

Edge detection is performed to different goals, some of them are:

Extract direction the Edge

corner detection

the effects of the stitched image (due to the lack of precision in placing multiple images together to achieve an integrated image, such as Google - Earth images).

Changing the image size, creating a new image of a part of an image(Crop), rotate it

Thresholding(change gray scale image to binary image)
