WIPO Patent Application WO/2018/058476
Kind Code:
A1
Abstract:
The invention relates to the field of image processing. Provided in an embodiment of the invention are an image correction method and device enabling image correction to be performed in a shorter period of time under a lighter load condition and improving real-time capability of correction on an image sequence. The solution provided in the embodiment of the invention comprises: capturing the i
th image, where i is a positive integer greater than or equal to 1; tracking, in the i
th image, and by means of an optical flow constraint equation, a quadrilateral region of an initial image, and acquiring a quadrilateral region of the i
