Abstract
Systems and methods of processing a retinal input image to identify an area representing a predetermined feature. One method comprises processing said retinal input image to generate a plurality of images, each of said plurality of images having been scaled by a respective associated scaling factor, and each of said plurality of images having been subjected to a morphological closing operation with a two-dimensional structuring element arranged to affect the image substantially equally in at least two perpendicular directions. The plurality of images are processed to identify said area representing said predetermined feature.
Claims37
A method of processing a retinal image to detect an area representing a bright spot, the method comprising:
- processing said image to remove linear structures and generate a processed image;
- and
- detecting said area representing a bright spot in said processed image.
A computer readable medium carrying computer readable instructions arranged to cause a computer to process a retinal image to detect an area representing a bright spot, the processing comprising:
- processing said image to remove linear structures and generate a processed image;
- and
- detecting said area representing a bright spot in said processed image.
Apparatus for processing a retinal input image to identify an area representing a bright spot, the apparatus comprising:
- a memory storing processor readable instructions;
- and
- a processor arranged to read and execute instructions stored in said memory;
- wherein said processor readable instructions comprise instructions arranged to cause the processor to:
- process said image to remove linear structures and generate a processed image;
- and
- detect said area representing a bright spot in said processed image.
A method of processing a retinal image to detect an area representing a bright spot, the method comprising:
- processing said retinal input image to generate a plurality of images, each of said plurality of images having been scaled by a respective associated scaling factor, and each of said plurality of images having been subject to a morphological operation.
A method of processing a retinal image to determine whether said image includes indicators of disease, the method comprising:
- locating at least one area representing a bright spot by processing said image to remove linear structures and generate a processed image and detecting said area representing a bright spot in said processed image.
A method of processing a retinal image to detect an area representing an exudate, the method comprising:
- processing said image to remove linear structures and generate a processed image;
- and
- detecting said area representing an exudate in said processed image.
A method of processing a retinal image to detect an area representing an exudate, the method comprising:
- processing said retinal input image to generate a plurality of images, each of said plurality of images having been scaled by a respective associated scaling factor, and each of said plurality of images having been subject to a morphological operation.
A method of processing a retinal image to determine whether said image includes indicators of disease, the method comprising:
- locating at least one area representing a bright spot by processing said image to remove linear structures and generate a processed image and detecting said area representing a bright spot in said processed image.
