Salience Preserving Image Fusion
First Claim
Patent Images
1. A method at least partially implemented by a computer, the method comprising:
- fusing multi-channel images into a single image based on importance-weighted gradients, each multi-channel image comprising multiple channels; and
wherein the importance weighted gradients are measured using respective salience maps for each channel in the multi-channel images.

Abstract
Salience-preserving image fusion is described. In one aspect, multi-channel images are fused into a single image. The fusing operations are based on importance-weighted gradients. The importance weighted gradients are measured using respective salience maps for each channel in the multi-channel images.

8. A computer-readable medium comprising computer-program instructions executable by a processor, the computer-program instructions, when executed, for performing operations comprising:
-
for each image in a set of source images, each image comprising multiple channels of pixel information, calculating a respective salience map of multiple salience maps for a gradient of each channel in the image; weighting, based on respective ones of multiple salience maps, respective contributions of each channel of the multiple channels to global statistics; and highlighting, based on weighted contribution of each channel to global statistics, gradients with high saliency in a target gradient to preserve salient features in a single image. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computing device comprising:
-
a processor; and a memory coupled to the processor, the memory comprising computer-program instructions executable by the processor for implementing operations comprising; receiving multiple multi-channel images, each multi-channel image comprising multiple channels of pixel information; and responsive to receiving the multi-channel images, fusing gradients from the multiple channels associated with each of the multi-channel images into a salience-preserving fused image, operations for fusing the gradients being based on local salience measurements for each pixel of the pixel information. - View Dependent Claims (16, 17, 18, 19, 20)
