Correlated pixel value.
Specifically, parameter is managed according to this, it can be according to processing relevant to the processing parameter in corresponding Processing Algorithm
Algorithm carries out parallel processing to the corresponding pixel value of each pixel in the first intermediate treatment picture, obtains each pixel
Corresponding correlated pixel value.
Wherein, by the way of parallel processing, the speed of operation can be promoted, and then improve the efficiency of picture processing.
Preferably, when the Processing Algorithm of the corresponding processing function of the processing parameter is the convolution algorithm that can symmetrically divide, root
According to the processing parameter, according to first direction Processing Algorithm, to each pixel on the first direction in the first intermediate treatment picture
The corresponding pixel value of point carries out parallel processing.Parameter is managed according to this, according to second direction Processing Algorithm, to the first intermediate treatment
The corresponding pixel value of each pixel in second direction in picture carries out parallel processing, the picture that obtains that treated, and first
Direction Processing Algorithm and second direction Processing Algorithm are that the corresponding Processing Algorithm of the processing function is carried out twocouese to split to obtain.
For example, the Processing Algorithm of the processing function can be split as to X-direction Processing Algorithm and Y direction processing calculation
Method.According to X-direction Processing Algorithm, to the corresponding pixel of each pixel in the X-direction in the first intermediate treatment picture
Value carries out parallel processing.According to Y direction Processing Algorithm, to each pixel in the Y direction in the first intermediate treatment picture
The corresponding pixel value of point carries out parallel processing.
Since the complexity of convolution algorithm is higher, so, the convolution algorithm that can symmetrically divide is divided into first direction processing
After algorithm and second direction Processing Algorithm, the complexity of calculating can be reduced, and then reduce the time calculated.
Further, if the Processing Algorithm of the corresponding processing function of the processing parameter is not the convolution algorithm that can symmetrically divide
When, then it does not need the Processing Algorithm carrying out twocouese fractionation, parameter can be directly managed according to this, according to the Processing Algorithm pair
The corresponding pixel value of each pixel in first intermediate treatment picture carries out parallel processing.
Step 207: by the unrelated picture of the corresponding correlated pixel value of each pixel and corresponding each pixel in caching
Plain value is added, the picture that obtains that treated.
Specifically, manage Function Identification according to this, from caching stored processing function mark nothing to do with pixel value it
Between corresponding relationship in, obtain the extraneous pixel values of each pixel.Again by the corresponding correlated pixel value of each pixel and nothing
It closes pixel value to be added, obtains each pixel treated pixel value, and then the picture that obtains that treated.
