Binary codes enable one to represent and process floor plans for houses made up of a lot of horizontal and vertical lines. Careful consideration is given to the following three items in view of these features: 1. A study of the "multistage separate coding" used as a method for reducing the number of binary digits required to represent image data made it clear that the coding has a big coefficient of compression. 2. For automatic adjustment of image angles, the "two-dimensional XOR processing (exclusive OR )" was used to judge whether the image was vertical or horizontal. And an algorithm was established for rotating the image only by addition and subtraction of positive integers. 3. Introduction of the degree of analogy calculated from the features of image configurations has conclusively revealed that the degree is useful in retrieving overlapped things drawn in plans.
