Abstract
PURPOSE:To detect at a high speed a linear part existing in an original image by classifying a phase by comparing whether density gradient vectors in the X direction and the Y direction, which is detected by a density gradient detecting mechanism are large or small, and deriving a quasi-angle from a ratio of a side prolongation and a radius of a circumscribed square. CONSTITUTION:The titled converter consists of a density gradient detecting mechanism 1 for detecting the density gradient vectors in the X direction and the Y direction by a differential processing from an original image, a phase classifier 2 for classifying a phase by comparing whether the density gradient vectors in the X direction and the Y direction, which is detected by this density gradient detecting mechanism 1 are large or small, and a quasi-angle calculator 3 for deriving a quasi-angle from a ratio of a side prolongation and a radius of a circumscribed square based on a result classified by this phase classifier 2. In such a way, a linear part existing in the original image can be detected.
