An attribute detecting apparatus of data signals obtains a block to which a mapped point belongs, for data signals divided into a plurality of blocks; sequentially repeats mapping processing in such a way that the mapped point belonging to the block is mapped to a similar region in the data signals previously allowed to correspond to the block (by setting an attribute detection position to an initial position of the mapped point and using the preceding mapping point as a new mapped point); and decides the attribute at the attribute detection position on the basis of position data of the mapping points obtained by the repeated mappings. An attribute detecting apparatus suitable for detecting the attributes of the fractal coded video signals can be realized.
A method for image representation such as segmentation using compressed image data, wherein an image is represented as a pixel value provided at each pixel in an image plane which is divided into a plurality of blocks, and said compressed data include at least position data of a similar region about each of said blocks, comprising:
A method for image reorientation such as edge detection using compressed data, wherein an image is represented as a pixel value provided at each pixel in an image plane, said image plane being divided into a plurality of blocks, and said compressed data including at least position data of a similar region about each block, comprising:
