FlatCam: Thin, Bare-Sensor Cameras using Coded Aperture and Computation
M. Salman Asif, Ali Ayremlou, Aswin Sankaranarayanan +2
FlatCam is a thin form-factor lensless camera that consists of a coded mask placed on top of a bare, conventional sensor array. Unlike a traditional, lens-based camera where an ima…
Fast Sublinear Sparse Representation using Shallow Tree Matching Pursuit
Ali Ayremlou, Thomas Goldstein, Ashok Veeraraghavan +1
Sparse approximations using highly over-complete dictionaries is a state-of-the-art tool for many imaging applications including denoising, super-resolution, compressive sensing, l…
Compensating Interpolation Distortion by Using New Optimized Modular Method
Mohammad Tofighi, Ali Ayremlou, Farokh Marvasti
A modular method was suggested before to recover a band limited signal from the sample and hold and linearly interpolated (or, in general, an nth-order-hold) version of the regular…
Optimized Spline Interpolation
Ramtin Madani, Ali Ayremlou, Arash Amini +1
In this paper, we investigate the problem of designing compact support interpolation kernels for a given class of signals. By using calculus of variations, we simplify the optimiza…
A proposed Optimized Spline Interpolation
Ramtin Madani, Ali Ayremlou, Arash Amini +1
The goal of this paper is to design compact support basis spline functions that best approximate a given filter (e.g., an ideal Lowpass filter). The optimum function is found by mi…
