| Abstract;In image processing, it is quite difficult to select image-processing filters to satisfy the conversion from original-image to its target-image. We previously proposed an image processing system named ACTIT (Automatic Construction of Tree-structural Image Transformation) that constructs image-processing filters to satisfy the given several image examples. ACTIT adopts GP (Genetic Programming), and it constructs tree-structured image-processing filter with pre-defined well-known filters including several ones, which require numerical parameters. It is difficult, however, to optimize both structure and parameters at the same time for the conventional GP. Thus, in this paper, we propose PT (Parameter Tunable)-ACTIT that can optimize structure and numerical parameter at the same time. GA (Genetic Algorithm) was adopted to optimize numerical parameters. Experimental results using PT-ACTIT show that we can construct a new filter, that we cannot construct using only pre-defined filters. They show better image processing filters to satisfy the given examples. (author abst.) |
