Abstract
Probabilistic measurements of objects in image data are obtained by analyzing individual segments of an image to determine the probability that an object is present in the segment, and aggregating the total probabilities among all of the segments in the image to provide an overall probabilistic measurement of the object. For example, pixels of an OCT image can be assigned probabilities that the pixel contains a retinal layer or background. The sum of probabilities of the retinal layer being present in a one-dimensional row of pixels gives a probabilistic length in that dimension of the retinal layer. Likewise, the sum of a two-dimensional array of pixels gives an area; and a three-dimensional array gives a volume.
Claims19
A method for measuring an object in an image, the method comprising:
- segmenting an image into a plurality of segments;
- obtaining a probabilistic value for each of the plurality of segments, the probabilistic value corresponding to a likelihood of an object being in each of the plurality of segments;
- and
- aggregating the probabilistic values from the plurality of segments to obtain a measurement for the object.
A system for measuring an object in an image, the system comprising:
- a processor operably coupled to a memory, the processor configured to:
- analyze a plurality of segments of an image to determine a probabilistic value corresponding to a likelihood of an object being present in the segment;
- and
- aggregate the probabilistic values from the plurality of segments to generate a measurement of the object.
