Problems solved by technology

However, the problem of human feature detection in image recognition is one of the most difficult problems in the field of object detection
In recent years, although researchers have devoted themselves to more effectively extracting the features of human body contour shape from images, and designing human body detection algorithms based on these features, so far, in the detection of bare human body organs such as palms, , often due to the complex background and the existence of a large number of similarly shaped objects, a large number of false detections occur

Embodiment 1

[0058] An embodiment of the present invention provides a human body feature detection method, specifically as figure 1 shown, including:

[0059] 101. The human body feature detection device acquires the first frame of pictures.

[0060] Specifically, in the human body feature detection method provided by the embodiment of the present invention, the human body feature detection device first obtains the first frame of picture, and the color format of the first frame of picture may be Red-Green-Blue (Red-Green-Blue, RGB) The color format may also be a luminance-chroma-saturation (Luminance-Chrominance-Saturation, YCrCb) color format, or a grayscale color format, which is not specifically limited in this embodiment of the present invention.

[0061] It should be noted that R in the RGB color format is the red channel component, G is the green channel component, B is the blue channel component, and RGB is the change of the three color channels of red, green and blue and the relat...

Abstract

The invention provides a human body feature detecting method and device, and the detecting method and device can improve the accurate rate of human body feature detecting. The method includes the steps that a first frame of picture is obtained; whether the color format of the first frame of picture is the luminance-chrominance-saturation YCrCb color format or not is determined; if the color format of the first frame of picture is the YCrCb color format, a first feature area in the first frame of picture is determined; pixel points in the first feature area are scanned to obtain the total number of the pixel points and the total number of complexion points; a first proportion which the total number of the complexion points accounts for the total number of the pixel points is calculated; if the first proportion is larger than a preset threshold value, features corresponding to the first feature area are determined as human body features. The human body feature detecting method and device are suitable for the field of detecting technologies.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a human body feature detection method and device. Background technique [0002] With the development of society, human feature detection has been widely used in many fields. However, the problem of human feature detection in image recognition is one of the most difficult problems in the field of object detection. In recent years, although researchers have devoted themselves to more effectively extracting the features of human body contour shape from images, and designing human body detection algorithms based on these features, so far, in the detection of bare human body organs such as palms, , often because the background is very complex and there are a large number of objects with similar shapes, resulting in a large number of false detections. Contents of the invention [0003] The invention provides a human body feature detection method and device, which can improve the ...
