the contour approximation algorithm

Variants

CHAIN_APPROX_NONE

stores absolutely all the contour points. That is, any 2 subsequent points (x1,y1) and (x2,y2) of the contour will be either horizontal, vertical or diagonal neighbors, that is, max(abs(x1-x2),abs(y2-y1))==1.

CHAIN_APPROX_SIMPLE

compresses horizontal, vertical, and diagonal segments and leaves only their end points. For example, an up-right rectangular contour is encoded with 4 points.

CHAIN_APPROX_TC89_L1

applies one of the flavors of the Teh-Chin chain approximation algorithm TehChin89

CHAIN_APPROX_TC89_KCOS

applies one of the flavors of the Teh-Chin chain approximation algorithm TehChin89
