DIGITAL IMAGE EDGE DETECTION
First Claim
Patent Images
1. A method of detecting edges, comprising:
- receiving an image including a plurality of pixels;
for each of the plurality of pixels, making a plurality of different edge assessments for that pixel, each different edge assessment considering that pixel in a different position of a different pixel patch; and
for each of the plurality of pixels, aggregating the different edge assessments for that pixel.

Abstract
Edges are detected in a digital image including a plurality of pixels. For each of the plurality of pixels, a plurality of different edge assessments are made for that pixel. Each different edge assessment considers that pixel in a different position of a different pixel patch. The different edge assessments for each pixel are aggregated.

12. A method of detecting edges, comprising:
-
receiving an image including a plurality of pixels; for each of the plurality of pixels, making a plurality of different edge assessments for that pixel, each different edge assessment considering that pixel in a different position of a different pixel patch, and each different edge assessment utilizing a structured forest including two or more decision trees, wherein different structured forests are used on different pixel patches; and for each of the plurality of pixels, aggregating the different edge assessments for that pixel. - View Dependent Claims (13, 14, 15)
