Abstract
An improved grid moving method using a selective pixel search method and an apparatus using the grid moving method which are capable of forming a grid with respect to an image of an object having a shape information and/or an image information, defining a unit region, moving the thusly formed grid, re-constructing an image grid, so that it is possible to reduce the number of blocks which are occupied by an object to be coded, thus significantly reducing the amount of computation and increasing a computation speed. The method includes the steps of forming a grid with respect to an image of an object having a predetermined shape, defining blocks each having a predetermined size, and moving the grid; a search and count step for selectively searching a pixel without searching all pixels, terminating the search when a pixel of the object is first searched, performing a step for determining the block in which an object exists as an object block with respect to the entire blocks, and counting the number of blocks in which the object exists; and determining a new grid start point having a minimum number of blocks in accordance with a result of the counting.
