An Information-Theoretic Ambient Occlusion
Ambient occlusion is a powerful technique that mimics indirect global illumination at a fraction of the cost. In this paper, we introduce a new ambient occlusion technique based o...

Signal-dependent raw image denoising using sensor noise characterization via multiple acquisitions
Accurate noise level estimation is essential to assure good performance of noise reduction filters. Noise contaminating raw images is typically modeled as additive white and Gauss...

Optimal Wavelet Transform for the Detection of Microaneurysms in Retina Photographs
In this article, we propose an automatic method to detect microaneurysms in retina photographs. Microaneurysms are the most frequent and usually the first lesions to appear as a co...

Optimal Zero-Aliasing Space Compaction of Test Responses
—Many built-in self-testing (BIST) schemes compress the test responses from a k-output circuit to q signature streams, where q << k, a process termed space compaction. The ...
