SYSTEMS AND METHODS FOR OBTAINING STRUCTURAL INFORMATION FROM A DIGITAL IMAGE |
| 摘要 |
A method for obtaining structural information from a digital image by an electronic device is described. The method includes obtaining a digital image. The method also includes determining a gradient vector for each pixel in a region of interest of the digital image. The method further includes transforming each pixel in the region of interest in accordance with a transform. Transforming each pixel includes determining, for each pixel, a first set of pixels. The first set of pixels includes any pixel along a line that is collinear with or perpendicular to the gradient vector and passes through a pixel location. Transforming each pixel includes incrementing with signed integer values, for each pixel, a first set of values in a transform space corresponding to any of the first set of pixels that are in a first direction of the line. |

1. A method for obtaining structural information from a digital image by an electronic device, comprising:
obtaining a digital image; determining a gradient vector for each pixel in a region of interest of the digital image; and transforming each pixel in the region of interest in accordance with a transform, comprising:
determining, for each pixel, a first set of pixels, wherein the first set of pixels comprises any pixel along a line that is collinear with or perpendicular to the gradient vector and passes through a pixel location, andincrementing, for each pixel, a first set of values in a transform space corresponding to any of the first set of pixels that are in a first direction of the line. |
