The fragment operation equipment includes that channel value captures sub- equipment, complexity parses sub- equipment and fragment filters sub- equipment, institute
It states the sub- equipment of channel value capture to connect with the sub- equipment of complexity parsing, the fragment filters sub- equipment and the complexity solution
Analyse sub- equipment connection.
6. as claimed in claim 5 pop one's head in from the vertical B ultrasound machine of shift-type, it is characterised in that:
The channel value captures sub- equipment for obtaining the red color channel value of each pixel in the edge enhanced images.
7. as claimed in claim 6 pop one's head in from the vertical B ultrasound machine of shift-type, it is characterised in that:
The complexity parses the gradient of all directions of red color channel value of the sub- equipment for determining each pixel to make
For red color channel value gradient, the corresponding scene of the edge enhanced images is determined based on the red color channel value gradient of each pixel
Complexity.
8. as claimed in claim 7 pop one's head in from the vertical B ultrasound machine of shift-type, it is characterised in that:
The fragment filters sub- equipment for being based on institute when the scene complexity received is more than or equal to default complexity threshold
It states scene complexity and determines the images fragment quantity that the edge enhanced images are carried out with average segmentation, the scene complexity is got over
Height, the images fragment quantity for carrying out average segmentation to the edge enhanced images is more, executes base respectively to each images fragment
It operates in the filtering processing of images fragment noise amplitude to obtain each filtering fragment, images fragment noise amplitude is smaller, to figure
As fragment execute filtering processing manipulation strength it is smaller, by it is each filtering fragment execute stitching portion smoothing processing concatenation with
It obtains fragment operation image and the fragment filters sub- equipment and is also used to be less than default complexity in the scene complexity received
When spending threshold value, filtering operation is executed to the edge enhanced images full image to obtain fragment operation image.
