More Information
Summary:The invention discloses an image enhancement method and apparatus, and a computer readable storage medium. The method comprises the steps of obtaining a to-be-enhanced image; extracting a high-frequency component of the image; calculating average pixel values of pixel points corresponding to the high-frequency components; and carrying out enhancement processing on pixel points with pixel values greater than or equal to the average pixel value in the image to obtain an enhanced image. By adoption of the image enhancement method and apparatus, image details can be enhanced, so that the image enhancement effect is improved. 本申请公开了一种图像增强的方法、装置及计算机可读存储介质，该方法包括：获取待增强的图像；提取所述图像的高频分量；计算所述高频分量对应的像素点的平均像素值；对所述图像中像素值大于或等于所述平均像素值的像素点进行增强处理，得到增强后的图像。采用本申请，可以对图像细节进行增强，以实现提高图像增强的效果。
