Embodiment Construction
[0038] The following examples are only used to illustrate the present invention, but are not intended to limit the application scope of the present invention:
[0039] A. Construct a capsule endoscopy image training sample library with labeled information, extract the global and local features of the capsule endoscopy small intestine image, and train a capsule endoscopy image classifier.
[0040] A.1 Extract the global features of the capsule endoscopic image, and train the global feature classifier.
[0041] 1) Use various computer means and techniques to collect images of capsule endoscopy of patients. Classify and sort endoscopic images by professional doctors, and mark whether there are lesions in the images; mark the lesion types for images with lesions (no need to mark the specific position of the lesion area in the image), and establish an in-capsule capsule with marked information Endoscopic image training sample library; in this embodiment, we use 2000 capsule endosc...
