Fast DCT-based image convolution algorithms and application to image resampling and hologram reconstruction
Convolution and correlation are very basic image processing operations with numerous applications ranging from image restoration to target detection to image resampling and geometrical transformation. In real time applications, the crucial issue is the processing speed, which implies mandatory use of algorithms with the lowest possible computational complexity. Fast image convolution and correl...
متن کاملFast, large-scale hologram calculation in wavelet domain
We propose a large-scale hologram calculation using WAvelet ShrinkAgeBased superpositIon (WASABI), a wavelet transform-based algorithm. An image-type hologram calculated using the WASABI method is printed on a glass substrate with the resolution of 65, 536×65, 536 pixels and a pixel pitch of 1μm. The hologram calculation time amounts to approximately 354 s on a commercial CPU, which is approxim...
متن کاملMultiplexed phase-conjugate holographic data storage with a buffer hologram.
We describe and demonstrate a volume holographic storage system in which a phase-conjugate object beam is reconstructed by the same reference beam that was used for recording. An intermediate hologram is used as a temporary buffer, recorded with its own reference beam and the data-bearing object beam. Reading this buffer hologram with the phase conjugate of its reference beam reconstructs the p...
متن کاملNon-iterative phase hologram computation for low speckle holographic image projection.
Phase-only spatial light modulators (SLMs) are widely used in holographic display applications, including holographic image projection (HIP). Most phase computer generated hologram (CGH) calculation algorithms have an iterative structure with a high computational load, and also are prone to speckle noise, as a result of the random phase terms applied on the desired images to mitigate the encodi...
متن کاملWatermarking Marbled Image Based on Linear Enhancement Hologram
A marbled image is generated by performing marbling operations on an image. When the marbled image is recovered to the original image, the parameters of the marbling operations should be known in the decoding process. By embedding these into the marbled image, we can eliminate an additional internet transmission. This paper proposes a watermark algorithm for marbled images based on a linear enh...
