Embodiment Construction

[0044] The embodiments of the present invention aim to solve the above-mentioned problems and provide an image processing device that can remove noisy edges from local edge information and thereby obtain contour images in which important object contours are enhanced.

[0045] Will refer to Figure 1 ~ Figure 12 An embodiment of the present invention will be described. First, use figure 1 The image processing apparatus 1 of this embodiment will be described as follows.

[0046] figure 1 The image processing device 1 shown in FIG. 1 obtains an input image P1, extracts the contour of an object included in the input image P1 based on the obtained input image P1, and outputs the extraction result. In addition, the input image P1 may be a static image or a moving image.

[0047] Such as figure 1 As shown, the image processing apparatus 1 has a storage unit 10, a control unit 20, an operation unit 41, and a display unit 42.

[0048] The storage unit 10 is used to store various data and prog...

Abstract

Disclosed are an image processing device and an image processing method 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 (1) includes a local contour extraction unit (23) which generates a local edge image (P12) and a global contour extraction unit (26) which generates a global edge image (P22). The image processing device generates a contour image (P30) by preparing the local edge image and obtaining the weighting sum of the local edge image and the global edge image (P22).

Description

[0001] Cross references to related applications [0002] This application claims the priority of Japanese Patent Application No. 2012-201971 filed on September 13, 2012, the entire content of which is incorporated herein for all purposes. Technical field [0003] The present invention relates to an image processing device, an image processing program, a computer-readable recording medium on which the image processing program is recorded, and an image processing method that generate a contour image representing the contour of an object shown in an input image. Background technique [0004] Conventionally, in the field of image processing, a technique for extracting the outline of an object included in an image has been known. Most of the conventional contour extraction technologies detect edges based on the local contrast information of the image to extract the contour of the object (calculate the direction and intensity of the edge (Patent Document 1); perform contour extraction pro...
