Abstract

The invention discloses an OLED mobile phone screen pixel positioning method based on region growth, and the method comprises the following steps: firstly searching a plurality of non-zero pixels in an input image as seed points, respectively carrying out the mapping of coordinates and pixel values, carrying out the upper, lower, left and right region search with the seed points as the reference,and searching a new seed till all lamp points are searched, thus implementing lamp point positioning; and meanwhile, filling the missing abnormal lamp point estimated row and column coordinates, and finally, enabling the image to be cut and subjected to odd or even column correction, so that the purpose of sorting discrete lamp point data is achieved. According to the method, positioning can be accurately completed mainly for the conditions that lamp points of the OLED screen are arranged in a staggered mode and the overall outline of the screen is irregular, and good robustness is achieved.

Description

technical field [0001] The invention belongs to the field of digital image processing, and more specifically relates to a method for positioning pixels of an OLED mobile phone screen based on region growth. Background technique [0002] First of all, OLED can be made into a flexible and transparent display, so that even though the prospect of OLED was not optimistic at one time, because of this irreplaceable advantage, OLED has been continuously researched and developed, so OLED technology has begun to widely enter the market today. . There are a wide variety of organic compounds and various structures, and OLED materials that meet various color and process requirements can be obtained, so that OLED displays can have rich colors to choose from. Thirdly, OLED has a simple structure and fewer production processes, which makes OLED displays have the potential for low-cost production. In addition, OLED displays also have many characteristics such as wide viewing angle, fast re...
