Interactive Illumination Invariance
This work addresses illumination invariance for computer vision applications, but it is incremental as it builds on prior automated methods by adding user interaction.
The paper tackles the problem of illumination effects disrupting computer vision algorithms by introducing an interactive system for generating illumination-invariant images, allowing users to specify and remove specific illumination variations, with evaluation results presented.
Illumination effects cause problems for many computer vision algorithms. We present a user-friendly interactive system for robust illumination-invariant image generation. Compared with the previous automated illumination-invariant image derivation approaches, our system enables users to specify a particular kind of illumination variation for removal. The derivation of illumination-invariant image is guided by the user input. The input is a stroke that defines an area covering a set of pixels whose intensities are influenced predominately by the illumination variation. This additional flexibility enhances the robustness for processing non-linearly rendered images and the images of the scenes where their illumination variations are difficult to estimate automatically. Finally, we present some evaluation results of our method.
