To represent the shape content of an image, the edgeorientation autocorrelogram is used.

It is proved that for a image subblock with a single straight edge, the DCT coefficient. energy compaction orientation and the spatial edgeorientation are not always orthogonal.
The measurement system on chain board of tooth shape chain was established based on computer vision, and a new kind of sub-pixel algorithm for edgeorientation of beeline and circle was put forward.
