Abstract: A method and device for detecting connected pixels in a two-dimensional (2D) image having a plurality of pixels each having X-Y coordinates may compare an upper-row pixel included in a Yth row with a lower-row pixel included in a Y+1th row depending on a comparison condition, wherein Y is a positive integer, and wherein when a difference in X coordinate between the upper-row pixel and the lower-row pixel is one or less, the upper-row pixel and the lower-row pixel are determined to be positioned adjacent each other, and when the difference in X coordinate is two or more, the upper-row pixel and the lower-row pixel are determined to be spaced apart from each other and update an index map that defines a relationship between index numbers of adjacent pixels depending on the determination to set pixels with the same or associated index number in the same pixel group.
