Method and system for feature extraction and decision making from series of images

摘要

Apparatus and methods comprise examination of a subject using images of the subject. The images can provide a non-invasive analysis technique and can include a plurality of images of a portion of the subject at different times a temperature stimulus applied to the subject. An image of the portion of the subject can be aligned such that each pixel of the image corresponds to the same point on the subject over a sequence of images of the portion. The sequence of images can be processed after aligning the images such that data is extracted from the images. The extracted data can be used to make decisions regarding the health status of the subject. Additional apparatus, systems, and methods are disclosed.

1. A method comprising:
acquiring images of a subject, the images including a plurality of images of a portion of the subject at different times; aligning an image of the portion of the subject such that each pixel of the image corresponds to a same point on the subject over a sequence of images of the portion; applying one or more calibration markers to the subject such that the one or more calibration markers are used when aligning the image of the portion of the subject, wherein the one or more calibration markers contain sharp corners resolved in the acquired images; processing the sequence of images after aligning the images such that data is extracted from the images; and presenting data corresponding to the subject on a display unit, following the processing of the sequence, wherein presenting the data includes, on the display unit displaying visualization data of a skin subject, aligning the visualization data to a scan of a biopsy of the skin subject corresponding to the visualization data of the skin subject.
