Multi-scale multi-camera adaptive fusion with contrast normalization

An apparatus for fusing images taken by a plurality of cameras, comprising:

• a processor configured for executing instructions comprising the steps of:
• receiving a plurality of images of the same scene taken by the plurality of cameras;
• generating saturation mask pyramids of the generated Laplacian pyramid images;
• applying contrast normalization to the Laplacian pyramids images based on the generated saturation mask pyramids;
• performing pixel-level fusion on the Laplacian pyramid images based on a local salience measure that reduces aliasing artifacts to produce one salience-selected Laplacian pyramid image for each pyramid level;
• and
• combining the salience-selected Laplacian pyramid images into a fused image.

A non-transitory computer-readable medium carrying one or more sequences for fusing images taken by a plurality of cameras, wherein execution of the one of more sequences of instructions by one or more processors causes the one or more processors to perform the steps comprising:

• receiving a plurality of images of the same scene taken by the plurality of cameras;
• generating saturation mask pyramids of the generated Laplacian pyramid images;
• applying contrast normalization to the Laplacian pyramids images based on the generated saturation mask pyramids;
• performing pixel-level fusion on the Laplacian pyramid images based on a local salience measure that reduces aliasing artifacts to produce one salience-selected Laplacian pyramid image for each pyramid level;
• and
• combining the salience-selected Laplacian pyramid images into a fused image.
