To improve the discrimination power of color indexing techniques we encode a minimal amount of spatial information in the index. We propose an approach that lies between uniformly tesselating the images with rectangular regions and relying on fully segmented images. For each image we define 5 partially overlapping, fuzzy regions. From each region in the image we extract the first three moments ...

Object recognition starts from a set of image measurements (including locations of points, lines, surfaces , color, and shading), which provides access into a database where representations of objects are stored. We describe a complexity theory of indexing, a meta-analysis which identiies the best set of measurements (up to algebraic transformations) such that: (1) the representation of objects...

In color TV broadcasting standards, such as NTSC and PAL, the limited bandwidth of the chrominance signals produces relatively slow chrominance transitions, causing smeared color edges in the received images. In this paper, we present an adaptive color transient improvement algorithm for enhancing color edge transition of images. By using a local image feature dependent gain control function to...

This study was performed to assess changes in skin color over 1 month after smoking cessation. The study population consisted of 49 men who participated in a smoking cessation program from March 2010 to June 2010 at a public health centre in Yangsan, South Korea. Thirty-four men who stop smoking completely were included in our study. Instrumental evaluations of skin color were performed using M...

This paper proposes a method to apply BPCSSteganography that we have already proposed for gray scale images to palette-based images which consists of a palette storing color vector information and an index image whose pixel value is corresponding to a index in the palette. A palette-based images can be represented by combining R G and B color component images. We embed secret information into t...

The paper presents the technique for image indexing and its parallel implementation on a parallel virtual machine. The indexing method is the combination of the autocorrelogram method and color difference correlograms method. Color filtering is used for quantization of the RGB colorspace into 64 colors to reduce the complexity and calculation time. Then, both color and spatial information are e...

We compare the dependences on the number of colors of the leading scattering amplitudes using the single index quark field and two index quark fields. These are seen to have different relationships to the scattering amplitudes suggested by chiral dynamics which can explain the long puzzling pion pion s wave scattering up to about 1 GeV. This may be interesting for getting a better understanding...
