Occlusion Resistant Image Template Matching Using Distance Transform |
| 摘要 |
A computing device performs matching between a target image and one or more template images. The computing device receives image data and performs an edge detection algorithm on the image data. The edge detection algorithm includes a distance metric based on angles between gradient vectors in the image data and gradient vectors in one or more templates. The computing device matches a building model to the image data based on results of the edge detection algorithm, wherein the building model is associated with the one or more templates. |

1. A method comprising:
receiving image data; performing an edge detection algorithm on the image data, wherein the edge detection algorithm includes a distance metric based on angles between gradient vectors in the image data and gradient vectors in one or more templates; and matching a building model to the image data based on results of the edge detection algorithm, wherein the building model is associated with the one or more templates. |
