Abstract
A method includes receiving image data and performing a non-maximum suppression (NMS) operation on the image data. The method also includes initiating an edge tracking by hysteresis (ETH) operation on a portion of the image data prior to completion of the NMS operation.
Claims20
A method comprising:
- receiving image data;
- performing a non-maximum suppression (NMS) operation on the image data;
- and
- prior to completion of the NMS operation, initiating an edge tracking by hysteresis (ETH) operation on a portion of the image data.
1 more element
An apparatus comprising:
- an image processor;
- and
- a memory storing instructions that are executable by the image processor to perform operations comprising:
- receiving image data;
- performing a non-maximum suppression (NMS) operation on the image data;
- and
- prior to completion of the NMS operation, initiating an edge tracking by hysteresis (ETH) operation on a portion of the image data.
4 more elements
A non-transitory computer-readable medium comprising instructions that, when executed by an image processor, cause the image processor to:
- receive image data;
- perform a non-maximum suppression (NMS) operation on the image data;
- and
- prior to completion of the NMS operation, initiate an edge tracking by hysteresis (ETH) operation on a portion of the image data.
