Using the Random Sprays Retinex Algorithm for Global Illumination Estimation

In this paper the use of Random Sprays Retinex (RSR) algorithm for global illumination estimation is proposed and its feasibility tested. Like other algorithms based on the Retinex model, RSR also provides local illumination estimation and brightness adjustment for each pixel and it is faster than other path-wise Retinex algorithms. As the assumption of the uniform illumination holds in many ca...

Exact Localization and Superresolution with Noisy Data and Random Illumination

This paper studies the problem of exact localization of multiple objects with noisy data. The crux of the proposed approach consists of random illumination. Two recovery methods are analyzed: the Lasso and the One-Step Thresholding (OST). For independent random probes, it is shown that both recovery methods can localize exactly s = O(m), up to a logarithmic factor, objects where m is the number...

Eye detection under varying illumination using the retinex theory

Eye detection plays an important role in face recognition because eyes provide distinctive facial features. However, illumination effects such as heavy shadows and drastic lighting change make it difficult to detect eyes well in facial images. In this paper, we propose a novel framework for illumination invariant eye detection under varying lighting conditions. First, we use adaptive candidate ...

Illumination Normalization of Face Image Based on Illuminant Direction Estimation and Improved Retinex

Illumination normalization of face image for face recognition and facial expression recognition is one of the most frequent and difficult problems in image processing. In order to obtain a face image with normal illumination, our method firstly divides the input face image into sixteen local regions and calculates the edge level percentage in each of them. Secondly, three local regions, which m...

Random Spray Retinex: A New Retinex Implementation to Investigate the Local Properties of the Model

In order to investigate the local filtering behavior of the Retinex model, we propose a new implementation in which paths are replaced by 2-D pixel sprays, hence the name “random spray Retinex.” A peculiar feature of this implementation is the way its parameters can be controlled to perform spatial investiga-tion. The parameters’ tuning is accomplished by an unsupervised method based on quantit...
