Abstract:
1. An image processing device comprising: a processor; and a memory which stores a plurality of instructions which, when executed by the processor, cause the processor to execute: acquiring a picked image; selecting pixels, which are adjacent to each other, to be connected based on value of the pixels in the image; generating a pixel connected area which includes the connected pixels, the generating including setting of an initial kernel size as a parameter used for generating the pixel connected area, performing opening on pixels in the initial kernel size, determining a rate of change in a number of pixels in the initial kernel size as a result of the opening, comparing the rate of change to a threshold value, and setting the initial kernel size as a desired kernel size or incrementing the initial kernel size until the desired kernel size is reached based on the comparing; extracting a feature point from an outer edge of the pixel connected area; and calculating a moved amount of the feature point on the basis of the feature point of a plurality of images that have been picked at the first time and the second time by the acquiring.
