Guided multi-exposure image fusion

An electronic device comprising:

• at least one processor;
• and
• at least one memory containing instructions that, when executed by the at least one processor, cause the electronic device to:
• obtain multiple images of a scene including a first image associated with a first exposure value and a second image associated with a second exposure value, each image comprising image data in each of multiple channels of a color space, the first exposure value greater than the second exposure value;
• decompose each channel of each image into a base layer and a detail layer;
• generate, for each image, a blending weight map for the base layer and a blending weight map for the detail layer;
• and
• combine the base layers and the detail layers based on the blending weight maps to obtain a high dynamic range (HDR) image of the scene.

A non-transitory computer-readable medium containing instructions that, when executed by at least one processor, cause an electronic device to:

• obtain multiple images of a scene including a first image associated with a first exposure value and a second image associated with a second exposure value, each image comprising image data in each of multiple channels of a color space, the first exposure value greater than the second exposure value;
• decompose each channel of each image into a base layer and a detail layer;
• generate, for each image, a blending weight map for the base layer and a blending weight map for the detail layer;
• and
• combine the base layers and the detail layers based on the blending weight maps to obtain a high dynamic range (HDR) image of the scene.
