In this paper, an automatic method for the detection of houses which represented black points on the large size scanned topographic map is described. Various signals such as characters, lines, signs, and dashed lines may overlapped with the house symbol. After contour detection method is used for detecting isolated houses. Run-length encoding method is used for manipulating houses touching with grid lines. Character and symbol elimination and morphological operations is done for the houses touched to roads and borderlines. Various recognition results are described.
