Problems solved by technology

[0003] However, when the traditional technology performs edge detection to extract the texture features of the image frame, it only refers to the single gray edge information in the image, resulting in some foreground edges being missed, resulting in a high false detection rate of texture features.

Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] In one embodiment, such as figure 1 As shown, a texture feature extraction method completely depends on computer programs and can run on a computer system based on the Von Neumann system.

[0042] The method includes:

[0043] Step S102, acquiring an input image, and converting the input image into an IHS color space.

[0044] An RGB image is an image identified by the data of the three color channels of R (red), G (green), and B (blue). In practical applications, images are usually RGB images, such as image frames in movies and video screens.

[0045] In this embodiment, according to th...

Abstract

The invention provides a textural feature extraction method. The textural feature extraction method includes the steps that an input image is obtained and converted into an HIS color space; a simple double-quaternion matrix of the image converted into the HIS color space is calculated; a preset multichannel filter functional matrix is obtained; a convolution matrix obtained by calculating the convolution of the simple double-quaternion matrix and simple double quaternions of the multichannel filter functional matrix; pixel coordinates with adjacent difference values smaller than a difference value threshold value in the convolution matrix are searched for, and textural features are generated according to the searched pixel coordinates. In addition, the invention provides a textural feature extraction device. The textural feature extraction method and device can reduce the false drop rate of textural feature extraction.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a texture feature extraction method and device. Background technique [0002] In various application scenarios in traditional technologies, it is usually necessary to perform edge detection on the texture in the image, so as to extract the texture features in the image that can represent the foreground of the object in the image. For example, in the application of converting 2D video to 3D video, it is usually necessary to perform edge detection on the foreground of the object in the video frame, extract its texture features, and then adjust its position in the video frame through inspection estimation, so that the human eye can produce 3D effect. [0003] However, when the traditional technology performs edge detection to extract the texture features of the image frame, it only refers to the single gray edge information in the image, resulting in some foreground edges ...
