A novel hierarchical approach to image retrieval is proposed. First, a color label histogram is used to e ectively lter out the images that are not similar to the query image in color. The proposed color label histogram built by categorizing the pixel colors is computationally much more e cient compared to other approaches. Next, the class parameters of those images passing the rst lter are use...

The color icon harnesses color and texture perception to create integrated displays of two-dimensional multi-parameter distributions. We have redesigned the color icon. The new design increases the number of parameters that can be integrated. It also extends the icon from two dimensions to three dimensions (which increases the number of parameters that can be integrated even further). To facili...

This paper proposes a construction of a new distance in the HSL color space by a combination of the distances of HSL scalar components and by using the fuzzy cmeans framework to derive a fuzzy color clustering method. The main contribution consists in introducing two particular parameters to control the balance between the hue distance and the luminosity distance in the color Euclidean distance...

This paper describes a new approach to adapted estimation of parametric mixture model based on diagonal of the modified Riesz distribution (DMRD) defined in R , r ≥ 2. The DMRD can model accurately a withe variety of color image. This parameters index a family of distribution witch include the bivariate Gamma and the convolution product between bivariate Gamma and univariate Gamma. In our work,...

In this paper, we adaptively model the appearance of objects based on Mixture of Gaussians in a joint spatial-color space (the approach is called SMOG). We propose a new SMOG-based similarity measure. SMOG captures richer information than the general color histogram because it incorporates spatial layout in addition to color. This appearance model and the similarity measure are used in a framew...

The effect of two anti-fungal treatments (metrafenone and boscalid + kresoxim-methyl) on the color and phenolic profile of Tempranillo and Graciano red wines has been studied. To evaluate possible modifications in color and phenolic composition of wines, control and wines elaborated with treated grapes under good agricultural practices were analyzed. Color was assessed by Glories and CIELab par...

This paper proposed a new algorithm to separate leukocytes from cytological image by setting parameters of lightness transformation based on the RGB color space, which can make the targets’ color in different areas. In our procedure, an operator is employed in using color features. According to their histogram distribution of hue component in HSL color space after enhancing the contrast of imag...

Color mixing occurs between background and foreground colors when a pattern is post-printed on a colored area because ink is not completely opaque. This paper proposes a new method for the correction of color mixing in line pattern such as characters and stamps, by using a modified particle density model. Parameters of the color correction can be calculated from two sets of foreground and backg...

A new color space, YCgCr, is described and applied for face detection. Although similar to the YCbCr color space, it differs in the use of the Cg color component instead of the Cb one. Here, the fundamentals of this new color space YCgCr are presented and its capabilities and advantages over YCbCr are analyzed. After describing the face extraction technique and the required decision values, the...

In this paper, we consider the problem of color restoration using statistical priors. This is applied to color recovery for underwater images, using an energy minimization formulation. Underwater images present a challenge when trying to correct the blue-green monochrome look to bring out the color we know marine life has. For aquatic robot tasks, the quality of the images is crucial and needed...
