Optical-lattice illumination patterns help in pushing high spatial frequency components of the sample into optical transfer function a collection microscope. However, exploiting these high-frequency require precise knowledge if reconstruction approaches similar to structured microscopy are employed. Here, we present an alternate blind approach that can provide super-resolution without requireme...

Natural lighting of buildings has an important morphofunctional value, since the human body is formed in natural environment. In modern conditions, additional with artificial light sources used a lack lighting, this leads to energy costs. The duration use day depends on many factors, including climate region. paper, authors propose approach preliminary assessment time taking into account differ...

The paper presents the object detection for dynamic texture scenes using illumination based techniques. They are two types of illumination technique. First one is illumination based background subtraction (ILBS) and second one is illumination based frame difference (ILFS). Illumination frame difference is identifying the objects accurately in dynamic texture scene compare to illumination backgr...

In order to make face recognition more reliable under varying illumination, a robust processing chain is presented in this paper. Most of the illumination normalization methods treat all face images in the same way without considering the specific illumination condition of each probe image. For the nearly welllit face images, they may be misclassified after illumination normalization. But they ...

Face detection and recognition depend strongly on illumination conditions. In this reported work, genetic algorithms are used to optimise parameters of the modified local normalisation and self-quotient image methods in cascade for illumination compensation to improve face recognition. The main novelty of the proposed method is that it applies to non-homogeneous as well as homogeneous illuminat...

Most of the recent color recognition/indexing approaches concentrate on establishing invariance to illumination color to improve the utility of color recognition. However , other eeects caused by illumination pose and specularity on three-dimensional object surfaces have not received notable attention. We present a chromaticity recognition method that discounts the eeects of illumination pose, ...

The appearance of objects depends on their material, shape, and on the illumination conditions. Conversely, object appearance provides us with cues about the illumination and the material. This so-called inverse problem is basically underdetermined and therefore we expect that material and illumination perception are confounded. To gain insight into the relevant mechanisms, we rendered a set of...

Illumination conditions have an explicit effect on the performance of face recognition systems. In particular, varying the illumination upon the face imposes such complex effects that the identification often fails to provide a stable performance level. In this paper, we propose an approach integrating face identity and illumination models in order to reach acceptable and stable face recognitio...

We describe a method of obtaining optical sectioning with a standard wide-field fluorescence microscope. The method involves acquiring two images, one with nonuniform illumination (in our case, speckle) and another with uniform illumination (in our case, randomized speckle). An evaluation of the local contrast in the speckle-illumination image provides an optically sectioned image with low reso...
