Automatic visual recognition of biological particles
First Claim
Patent Images
1. A method for recognizing biological particles, comprising:
- obtaining an image comprising biological particles;
detecting one or more parts of the image as containing one or more particles of interest;
extracting one or more feature vectors from each detected part of the image;
applying one or more non-linearities to each feature vector; and
classifying each part of the image into a category of biological particle based on the one or more feature vectors for each part of the image.

Abstract
A method and system provide the ability to automatically recognize biological particles. An image of biological particles (e.g., airborne pollen or urine) is obtained. One or more parts of the image are detected as containing one or more particles of interest. Feature vector(s) are extracted from each detected part of the image. Non-linearities are applied to each feature vector. Each part of the image is then classified into a category of biological particle based on the one or more feature vectors for each part of the image.
