As a preliminary step of many applications, skin detection serves as an irreplaceable role in image processing applications, such as face recognition, gesture recognition, web image ̄ltering, and image retrieval systems. Combining information from multiple color spaces improves the recognition rate and reduces the error rate because the same color is represented di®erently in other color spaces....

The purpose of color constancy algorithms is to estimate the illumination color reflected from an object and then eliminate it, making the color of the object appearance identical to the object actual color. To accomplish the purpose, we have developed a color constancy algorithm which is extended from Finlayson et al’s algorithm. By combining varying illumination constraint, Planckian locus wh...

Combining unique cytoprobe, rapid hemacyte fractionation, and novel color image analysis, The White IRIS (TWI) extends automated intelligent microscopy to leukocyte differentiation. TWI provides flow cytometry precision and microscopical resolution to review specimens flagged by hematology analyzers with differential capabilities or to complement other analyzers without these capabilities. The ...

This study we focus on the morphological-based image segmentation problem, based on the watershed pre-segmentation with color-alone feature. Based on the color mathematical morphology (MM) method, the similarity measure of merging process between neighboring pixels and regions can be performed as a ranking problem. To avoid the creation of a false color and false segmentation, a hybrid-ordering...

Bone marrow (BM) reticulin fibrosis (RF), revealed by silver staining of tissue sections, is associated with myeloproliferative neoplasms, while tools for quantitative assessment of reticulin deposition throughout a femur BM are still in need. Here, we present such a method, allowing via analysis of hundreds of composite images to identify a patchy nature of RF throughout the BM during disease ...

We propose a new model called the “composite model” to represent spectral functions. This model is built on the idea of decomposing all spectral functions into smooth and spiky components, each with its own distinct representation. A smooth spectrum can be expressed with coefficients of a set of given basis functions, and the discrete spikes in a spiky spectrum with their locations and heights....

Image retrieval based on color histograms requires quantization of a color space. Uniform scalar quantization of each color channel is a popular method for the reduction of histogram dimensionality. With this method, however, no spatial information among pixels is considered in constructing the histograms. Vector quantization (VQ) provides a simple and effective means for exploiting spatial inf...

Most current approaches to multiantigen fluorescent imaging require overlaying of multiple images taken with separate filter sets as a result of differing dye excitation requirements. This requirement for false-color composite imaging prevents the user from visualizing multiple species in real time and disallows imaging of rapidly moving specimens. To address this limitation, here we investigat...

A novel system of optical see-through augmented reality (AR) is proposed by making use of a holographic optical element (HOE) with full-color and lens-array functions. The full-color lens-array HOE provides see-through property with three-dimensional (3D) virtual images, for it functions as a conventional lens array only for Bragg-matched lights. An HOE recording setup was built, and it recorde...

Herein, a stepwise electrodeposition technique was used to synthesize the Pd based nanoparticles on indium-tin oxide (ITO) electrodes. First of all, Pd nanoparticles were electrodeposited on ITO via one step electrodeposition technique. Furthermore, Au was electrodeposited on Pd. Finally, Co was electrodeposited on Au and Pd electrodeposited ITO electrode via stepwise electrodeposition techniqu...
