Zusammenfassung: | To provide an area boundary line detection device capable of detecting a boundary line by complementing the boundary line in an image in which the boundary line is hard to detect, and also to provide a method thereof and a program thereof, and a region splitting processing device having the area boundary line detection device.SOLUTION: The area boundary line detection device includes: a complementary image generation part 121 configured to implement image processing including a low-resolution step for lowering a resolution to an edge processing image obtained by applying edge detection processing to an image in order to detect a boundary line of a prescribed subject taken in the image so as to generate an edge complementary image with an edge undetected at the edge detection processing generated; and an edge composite image generation part 122 configured to composite the edge processing image and the edge complementary image generated at the complementary image generation part 121 to generate an edge composite image.SELECTED DRAWING: Figure 1
【課題】本発明は、境界線を検出し難い画像でも境界線を補完することによって境界線を検出できる領域境界線検出装置、該方法および該プログラムならびに前記領域境界線検出装置を備えた領域分割処理装置を提供する。【解決手段】本発明のる領域境界線検出装置は、画像に写り込んだ所定の被写体の境界線を検出するために前記画像をエッジ検出処理したエッジ処理画像に、解像度を低下させる低解像度化処理を含む画像処理を実施することによって、前記エッジ検出処理で未検出のエッジを生成したエッジ補完画像を生成する補完画像生成部121と、前記エッジ処理画像と前記補完画像生成部121で生成したエッジ補完画像とを合成することによって、エッジ合成画像を生成するエッジ合成画像生成部122とを備える。【選択図】図1 |
