Problems solved by technology

[0005] Among them, skin color detection based on color space is widely used in the field of real-time stream processing due to its fast and efficient characteristics, but its accuracy is low. Skin color detection based on machine learning classification and skin color detection based on deep learning image segmentation have relatively low High accuracy, but performance often becomes a bottleneck in real-time stream processing, and it is difficult to apply to situations where devices such as mobile terminals are limited

Embodiment 1

[0033] figure 1 This is a flowchart of a skin color detection method provided in Embodiment 1 of the present invention. This embodiment is applicable to the case where the color value of face data is used as prior knowledge for skin color detection, and the method can be executed by a skin color detection device, The skin color detection device can be implemented by software and / or hardware, and can be configured in a mobile terminal, for example, a mobile phone, a tablet computer, a smart wearable device (such as a smart watch, smart glasses, etc.), etc., and specifically includes the following steps:

[0034] Step 101: Collect video data.

[0035] In this embodiment, the video data waiting for skin color detection generally refers to video data generated, transmitted or played in a real-time service scenario.

[0036] Generally speaking, skin color detection can be performed on the video data in the mobile terminal that generates the video data. At this time, the camera of ...

Embodiment 2

[0140] Image 6 It is a structural block diagram of a skin color detection device provided in Embodiment 2 of the present invention, which may specifically include the following modules:

[0141] A video data collection module 601, configured to collect video data, the video data includes multiple frames of image data;

[0142] A face data detection module 602, configured to detect face data in multiple frames of the image data respectively;

[0143] The mapping function correction module 603 is used for, if face data is detected in the first target image data, the color value of the face data is used as a priori knowledge to correct the mapping function, and the mapping function is used to identify based on the color value skin data, the first target image data is image data collected at a first time point;

[0144] The mapping detection module 604 is used for substituting the color value of the second target image data into the mapping function, so as to detect skin data i...

Embodiment 3

[0189] Figure 7 This is a schematic structural diagram of a mobile terminal according to Embodiment 3 of the present invention. Figure 7 A block diagram of an exemplary mobile terminal 12 suitable for use in implementing embodiments of the present invention is shown.

Abstract

The embodiment of the invention provides a skin color detection method and device, a mobile terminal and a storage medium, and the method comprises the steps of collecting video data which comprises multiple frames of image data, respectively detecting face data in the multiple frames of image data, and if the face data is detected in first target image data, correcting a mapping function by taking the color value of the face data as priori knowledge, the mapping function being used for identifying the skin data based on the color value; and substituting the color value of the second target image data into the mapping function to detect the skin data in the second target image data. Accurate color values are calculated for skin data in the current business scene, so that the mapping function is adaptively corrected, and the accuracy of skin color detection of the mapping function in the current business scene can be improved; in addition, operations such as human face detection, statistics of color values of skin data, correction and application of mapping functions and the like are simple, the calculation amount is small, the speed is high, and consumed time is short.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of computer vision, and in particular, to a skin color detection method, device, mobile terminal, and storage medium. Background technique [0002] With the rapid development of mobile Internet and mobile terminals, video data in mobile terminals has become a common information carrier in human activities, such as live broadcasts, video calls, etc. They contain a large amount of information about objects and become a way for people to obtain original information from the outside world. one. [0003] For these video data, users usually choose beauty, and skin color detection is the basis of beauty, which determines that beauty can realize real-time processing of video data, and also feels that the effect of beauty is good or bad. [0004] The existing mainstream skin color detection can be divided into skin color detection based on color space, skin color detection based on machine lear...
