Binary mask programmable hologram.
We report, for the first time, the concept and generation of a novel Fresnel hologram called the digital binary mask programmable hologram (BMPH). A BMPH is comprised of a static, high resolution binary grating that is overlaid with a lower resolution binary mask. The reconstructed image of the BMPH can be programmed to approximate a target image (including both intensity and depth information)...
متن کاملTest Generation for the Binary Floating Point Add Operation With Mask-Mask-Mask Constraints
The mathematical problem discussed is important for generating test cases in order to debug floating point adders designs. Floating point numbers are assumed to be written as strings of {0, 1} bits, in a format compatible with IEEE standard 754. A mask is a string of characters, composed of {′0′,′ 1′,′ x′}. A number and a mask are compatible if they have the same length and each numerical chara...
متن کاملBinary mask estimation based on frequency modulations
In this paper, a binary mask estimation algorithm is proposed based on modulations of speech. A multi-resolution spectrotemporal analytical auditory model is utilized to extract modulation features to estimate the binary mask, which is often used in speech segregation applications. The proposed method estimates noise from the beginning of each test sentence, a common approach seen in many conve...
متن کاملTechniques for Estimating the Ideal Binary Mask
This paper provides a comparison of binary mask estimation techniques, based on different ways of estimating the instantaneous SNR. The effect of six different gain functions and three noise estimation algorithms on estimating the SNR, and subsequently the binary mask was assessed. New criteria are proposed for classifying time-frequency bins as belonging to the target or masker signals. Senten...
متن کاملMorphological Binary Interpolation with Convex Mask
In the paper an image interpolation method based on the mathematical morphology is proposed. The method deals with binary images and allows transforming one input binary object into another one. The proposed method is an improvement of the Hausdorff distance approach. Two ways of improvement are proposed. The first one allows controling more precisely the process of object growing during the in...
