______ operation takes a single input image into a single output image in such a way that each output pixel's gray level depends only upon the gray level of the corresponding input pixel.
举一反三
- CCD sensor is poor in terms of sensitivity and image quality. The reason is that each pixel of CCD needs an A/D, which reduces the photosensitive area of each pixel. In addition, the use of pixel equivalent A/D converter will also cause high noise interference. ( )
