After S120, this embodiment also includes: S130, save the beauty Edited photos, or save edited photos and selected photos. For the display interface of this embodiment, reference may be made to the display interface shown in FIG. 2 .
本发明上述各实施例提供的图像处理方法可以选择性的对终端设备的显示界面中的部分或全部人脸进行美颜处理，并且可以对不同人脸执行不同程度的美颜处理，而不是以同一程度对图像中所有人脸进行美颜处理的单一方式，该处理方式可以让图像中的某一个人或者多个人比其他人更“美”，增加了美颜相机APP的智能性、灵活性和可操作性。The image processing methods provided by the above-mentioned embodiments of the present invention can selectively perform beautification processing on some or all of the faces in the display interface of the terminal device, and can perform different degrees of beautification processing on different faces, instead of using A single method of beautifying all faces in the image to the same degree. This processing method can make one or more people in the image more "beautiful" than others, increasing the intelligence and flexibility of the beauty camera APP and operability.
需要说明的是，本发明上述各实施例在具体实现中，终端设备中配置的人脸识别技术的算法效率和处理器处理速度，决定了人脸识别的速度和准确性，由于终端设备的处理器通常需要处理大量APP的请求和服务，工作任务非常繁重，如果再进行大量数字图像数据的处理，处理能力会变得捉襟见肘，不仅影响APP的响应速度，人脸识别的效率也会很低，通常可以在终端设备中添加额外的处理单元辅助处理数字图像数据，例如在终端设备中添加一个专门用于处理数字图像数据的处理单元，比如数字信号处理(Digital SignalProcessing，简称为：DSP)单元，这样既能减少终端设备的主用处理器的工作负担，同时也提高了人脸识别的效率。It should be noted that, in the specific implementation of the above-mentioned embodiments of the present invention, the algorithmic efficiency and processor processing speed of the face recognition technology configured in the terminal device determine the speed and accuracy of face recognition. The server usually needs to process a large number of APP requests and services, and the work tasks are very heavy. If a large amount of digital image data is processed, the processing capacity will become stretched, which will not only affect the response speed of the APP, but also the efficiency of face recognition will be very low. Usually, an additional processing unit can be added to the terminal device to assist in processing digital image data, for example, a processing unit dedicated to processing digital image data, such as a digital signal processing (Digital Signal Processing, referred to as: DSP) unit, can be added to the terminal device. This can not only reduce the workload of the main processor of the terminal device, but also improve the efficiency of face recognition.
还需要说明的是，通过人脸识别技术识别出的人脸区域通常不能太大也不能太小，如果人脸识别区域远大于人脸实际区域会导致对人脸进行美颜处理时，处理的数据量增多而影响美颜算法效率；相反如果人脸识别区域小于人脸实际区域会导致美颜算法进行瘦脸和美肤处理时效果不佳；通常可以通过调整坐标参数，或者根据人脸面积获取人脸识别区域的最佳效果。It should also be noted that the face area recognized by face recognition technology is generally neither too large nor too small. If the face recognition area is much larger than the actual area of the face, it will cause the face to be beautified. The increase in the amount of data will affect the efficiency of the beautification algorithm; on the contrary, if the face recognition area is smaller than the actual area of the face, the effect of the beautification algorithm for face thinning and skin beautification will be poor; usually, the coordinate parameters can be adjusted, or the face area can be obtained according to the face area. The best results in the face recognition area.
