IMAGE PROCESSING DEVICE, COMPUTER-READABLE RECORDING MEDIUM, AND IMAGE PROCESSING METHOD

摘要

Disclosed are an image processing device, an image processing method, and a non-transitory computer-readable medium that obtain a contour image in which noise edges are eliminated from local edge information and a contour of an important object is enhanced. The image processing device includes a local contour extraction unit which generates a local edge image and a global contour extraction unit which generates a global edge image. The image processing device generates a contour image by preparing the local edge image and obtaining the weighting sum of the local edge image and the global edge image.

主权项

1. An image processing device for generating a contour image showing a contour of an object shown in an input image, the image processing device comprising:
a local edge image generator configured to generate a local edge image showing a local edge of the object in the input image based on contrast between a region in the input image and a region adjacent to the region; a saliency edge image generator configured to generate a contrast map image showing a salient region within the input image and generate a saliency edge image showing an edge included in the generated contrast map image; and a contour image generator configured to generate the contour image by combining the local edge image and the saliency edge image.
