Image detection apparatus and image detection method capable of detecting roundish shape |
摘要 |
An image detection apparatus includes a filter operation unit for conducting an operation of calculating a synthetic product between inputted image data and a plurality of filters, wherein respectively, the filters differ in direction. And having respective orientations a directional balance operation unit includes an angle calculation unit for obtaining an angle made between a vector whose components are a plurality of outputs of the filter operation unit for each directions and a reference vector whose components are equal to each other. A rounded convex region detection unit detects rounded convex regions within the inputted image based on an output of the directional balance calculation unit.
