vesselness PV
function vid=vesselness_PV(vid,use_parallel,sz,norm)
Description
This function enhances blood vessels in an input image or video using frangi filtering. It supports both sequential and parallel processing.
| Parameter Name |
Type |
Description |
| vid |
2D/3D array |
Input image or video as a 2D or 3D array. |
| use_parallel |
Boolean |
(Optional) Boolean flag to enable parallel processing (default: 1). |
| sz |
Vector |
(Optional) Scale range for the vesselness filter (default: 0.5:0.5:2). |
| norm |
Boolean |
(Optional) Normalization flag for vesselness filtering (default: 0). |
Function Outputs:
| Parameter Name |
Type |
Description |
| vid |
2D/3D array |
Image or video with enhanced blood vessels. |
Example usage:
vid_filtered = vesselness_PV(vid); % Default parameters with parallel processing
vid_filtered = vesselness_PV(vid, 0, 0.5:0.5:2, 1); % Sequential processing with normalization
Notes:
- Uses vesselness filtering to enhance tubular structures in images.
- Parallel processing is available for large videos to improve efficiency.
- Normalization ensures that vessel structures are highlighted consistently.
