<p>PROBLEM TO BE SOLVED: To decompose received image information properly for coding with smaller data amount. SOLUTION: A parameter decision section 1 decides a parameter for multi- layer display of an input image. An image reduction section 2 uses a desired reduction filter to reduce an image for the multi-layer display whose parameter is decided. A ridge extract section 3 conducts Laplace arithmetic operation to seek a ridge with respect to the reduced image so as to detect a unit ridge and detects a macro ridge based on the detected unit ridge and calculates the intensity of ridge for each rectangular area enclosing the detected macro ridge.</p> |
