Continuous wavelet transform of multiview images using wavelets based on voxel patterns
This work addresses image processing for autostereoscopic 3D displays, which is an incremental improvement in a domain-specific application.
The authors tackled the problem of processing multiview images for autostereoscopic 3D displays by proposing wavelets based on voxel patterns, performing direct and inverse continuous wavelet transforms on binary and grayscale images. The result was that restored images correctly reproduced the multiview structure, and modified images with adjusted parallax and depth produced corresponding visual 3D effects when displayed using lenticular plates.
We propose the multiview wavelets based on voxel patterns of autostereoscopic multiview displays. Direct and inverse continuous wavelet transforms of binary and gray-scale images were performed. The input to the inverse wavelet transform was the array of wavelet coefficients of the direct transform. A restored image reproduces the structure of the multiview image correctly. Also, we modified the dimension of the parallax and the depth of 3D images. The restored and modified images were displayed in 3D using lenticular plates. In each case, the visual 3D picture corresponds to the applied modifications. The results can be applied to the autostereoscopic 3D displays.
