Problems solved by technology

This method uses the S channel in the HSV color space of the image to extract the outline of the target, but due to the lack of assistance from other channels, the color of the target area cannot be extracted and the background color can be filtered

Embodiment Construction

[0036] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0037] The invention provides a method for extracting wood regions and main colors based on images, comprising the following steps:

[0038] Step S1, collecting target wood image samples through a camera;

[0039] Step S2, for the wood image sample, use a contour detection algorithm (the contour detection algorithm includes image grayscale, filtering, edge detection process) to detect the contour of the wood, and on the basis of contour detection, shrink a certain pixel inward , to ensure that all the pixels on the picture are the pixels of the target;

[0040] Step S3, converting the color space of all timber images from RGB to HSV or HLS;

[0041] Step S4, separate the three channels of the HSV color space, calculate the histogram data vector of the H channel of each picture, the histogram data vector of the S channel, the histogram d...

Abstract

The invention relates to an image-based wood region and main color extraction method. Through sample collection, proper parameters can be generated according to different production environments and shooting conditions, and a tedious parameter adjustment process is not needed. According to the method, pixel-level and irregular target area extraction can be achieved, irrelevant colors are efficiently filtered out, and therefore wood main color extraction is achieved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image-based method for extracting wood regions and main colors. Background technique [0002] In the field of image processing, target area extraction refers to the process of using certain techniques and methods to achieve target contour extraction in digital images containing targets and backgrounds, ignoring the influence of background and target internal textures and noise interference. It is an important basis for technologies such as object detection, shape analysis, object recognition, and object tracking. [0003] At present, in the field of industrial inspection, the detection and extraction of target areas generally start from two aspects: one is to extract from the technical level of image segmentation; the other is to find and sort visually sensitive areas by simulating the visual characteristics of the human eye region of interest in the image. Edge det...
