Method for characterizing images acquired through a video medical device
According to a first aspect, the invention relates to a method to support clinical decision by characterizing images acquired in sequence through a video medical device. The method comprises defining at least one image quantitative criterion, storing sequential images in a buffer, for each image ( 10 ) in the buffer, automatically determining, using a first algorithm, at least one output based on said image quantitative criterion and attaching said output to a timeline ( 11 ).
1. A method to support clinical decision by characterizing images acquired in sequence through a medical device, comprising:
storing images in a buffer;
for each image in the buffer, automatically determining, using a first algorithm, at least one output based on at least one image quantitative criterion,
wherein the at least one image quantitative criterion is one selected from the group consisting of kinematic stability, similarity between images, probability of belonging to a category, image or video typicity, image or video atipicity, image quality, and presence of artifacts, and
wherein the at least one output of the first algorithm comprises a cluster associated with each image; and
extracting, from the buffer, the images according to said at least one output for each image.
2. The method according to claim 1 , wherein the at least one output of the first algorithm is a boolean, scalar or vector value.
3. The method according to claim 1 , wherein a timeline is formed of temporal regions corresponding to images with equal outputs.
4. The method according to claim 3 , wherein said timeline is formed of temporal regions corresponding to consecutive images with said equal outputs.
5. The method according to claim 1 , further comprising:
selecting images with equal said at least one output of the first algorithm; and
processing the selected images using a second algorithm, the second algorithm being configured to provide at least one second output.
6. The method according to claim 5 , further comprising:
displaying said at least one second output.
7. The method according to claim 5 , wherein the second algorithm is a content-based image or video retrieval algorithm.
