    • A method and a system for adaptive image enhancement are provided for measuring the image quality of a pixel region in a frame, performing an image classification based on the image quality measurement, and enhancing image quality by applying operations according to image classification of the region. Also provided is a method as above including the steps of dividing a frame into P pixel regions; and for each one of the pixel regions measuring the image quality; assigning an image quality class; and enhancing the image. Also provided is a system for adaptive image enhancement including a circuit to measure the image quality of a pixel region in a frame in a source video image; a circuit to perform an image classification of the region based on the image quality measurement; and a circuit to enhance the image quality of the region in the source video image a by applying operations based on the image classification of the frame.
    • 提供一种用于自适应图像增强的方法和系统,用于测量帧中的像素区域的图像质量,基于图像质量测量执行图像分类,并且通过根据该区域的图像分类应用操作来提高图像质量。 还提供了如上所述的方法,包括以下步骤:将帧分割成P个像素区域; 并且对于测量图像质量的每个像素区域; 分配图像质量等级; 并增强形象。 还提供了一种用于自适应图像增强的系统,其包括用于测量源视频图像中的帧中的像素区域的图像质量的电路; 基于图像质量测量执行区域的图像分类的电路; 以及通过基于帧的图像分类的操作来增强源视频图像a中的区域的图像质量的电路。
