MOTIVATION In microarray gene expression studies, the number of replicated microarrays is usually small because of cost and sample availability, resulting in unreliable variance estimation and thus unreliable statistical hypothesis tests. The unreliable variance estimation is further complicated by the fact that the technology-specific variance is intrinsically intensity-dependent. RESULTS Th...

This work presents a high-resolution image acquisition system by combining a multi-camera imaging system composed of multiple low-resolution digital cameras and a color super-resolution image reconstruction algorithm. Aligned and adjusted multiple mini-cameras and the controlling system consist the multi-camera imaging system. Some of the cameras obtain intensity information and the other ones ...

Vehicle Color Recognition System is the implementation of automatic detection of predominant color of vehicles from the traffic images captured through CCTV cameras installed at crossings. This document presents a new effective method for extracting color of vehicle using MATLAB, Firstly vehicle is cropped automatically from the traffic image and then color of individual vehicle is picked accor...

X-ray binaries exhibit a wide range of properties but there are few accepted methods to determine the nature compact object. Color-Color-Intensity diagrams have been suggested as means distinguishing between systems containing black holes from those neutron stars. However, this technique has verified with data only one instrument (RXTE/ASM) single set colors defined using available in pre-deter...

despite the potential of high intensity ultrasound treatment on homogenization of milk and dairy based products, this treatment, under certain conditions, may lead to produce off-odors which can influence its applicability in the food industry. therefore, in this research, cacao flavored milk (chocolate milk) was treated using ultrasound at various levels of power intensity, exposure time, and ...

This paper presents a novel image enhancement algorithm using a multilevel windowed inverse sigmoid (MWIS) function for rendering images captured under extremely non uniform lighting conditions. MWIS based image enhancement is a combination of three processes viz. adaptive intensity enhancement, contrast enhancement and color restoration. Adaptive intensity enhancement uses the non linear trans...

The browning kinetic was recorded using color data information from images of avocado slices. GLCM image texture was used to describe the reaction. In the experiment, images of avocado slices stored at 4°C were captured and saved in tiff format. The classical color intensity index (the mean L* value) and some statistics GLCM image textures were used. Results showed that it is possible to use GL...

SPECT detects γ-rays from administered radiopharmaceutical within the patient body. γ-rays pass through different tissues before reaching detectors and are attenuated. Attenuation can cause artifacts; therefore different methods are used to minimize attenuation effects. In our study efficacy of Chang method was evaluated for attenuation purpose, using a custom made heart phantom. Due to d...

Existing color constancy methods cannot handle both uniformly colored surfaces and highly textured surfaces in a single integrated framework. Statistics-based methods require many surface colors and become error prone when there are only a few surface colors. In contrast, dichromatic-based methods can successfully handle uniformly colored surfaces but cannot be applied to highly textured surfac...

Optical correlation has traditionally processed monochromatic gray-scale images. This paper develops a new encoding mechanism that uses the chromaticity of the input signal. It is then not only possible to detect different colored objects, but the system is also invariant to changes in the brightness of the lighting, including variations across the object.
