This paper describes a comparative study of color image segmentation for various color spaces such as RGB, YUV, XYZ, Lab, HSV, YCC and CMYK using Dynamic Histogram based Rough Fuzzy C Means (DHRFCM). The proposed algorithm DHRFCM is based on modified Rough Fuzzy C Means (RFCM), which is further divided into three stages. In the pre-processing stage, convert RGB into required color space and the...

A framework for clustered-dot color halftone watermarking is considered, wherein watermark patterns are embedded in individual colorant halftones prior to printing and embedded watermarks are detected from scans of the printed images after obtaining estimates of the individual halftone separations. The principal challenge in this methodology arises in the watermark detection phase. Typical thre...

This short presentation paper describes an exploration and the visualisation of virtual 3D compositions through custom developed software and fine art printmaking. The author, a trained and practising visual artist considers this innovative visualisation as an exploration into the newly emerging visual language of the computer in similar vein to some of the NPR artists. The comprehension of vir...

Skin detection is one of the most important and primary stages in some of image processing applications such as face detection and human tracking. So far, many approaches are proposed to done this case. Near all of these methods have tried to find best match intensity distribution with skin pixels based on popular color spaces such as RGB, CMYK or YCbCr. Results show these methods cannot provid...

Confidentiality is the most important aspect of information security. Visual Cryptography (VC) is a decryption-less cryptographic technique where human eye is proficient in decrypting the secret information. VC is implemented for binary, gray scale and color images, Color image VC schemes are commonly implemented using Cyan-Magenta-Yellow-Black (CMYK) model that requires a computational device ...

CMYK 281 cornerstone of the therapy for neurosarcoidosis. Steroid therapy is usually started at a high dose and after achieving a clinical response, the dose is gradually tapered. Alternative therapeutic agents are indicated in patients with steroid sideeffects or lack of response to treatment or in cases where steroids are contraindicated. These include cyclosporine, azathioprine, hydroxychlor...

We present a method to include watermarks in printed images. Under specific viewing conditions and accurate printer calibration, the same color printed using different gray component replacement strategies (GCR) will look the same. We spatially vary the GCR along the image in a manner that is not perceptible, and we employ an estimation method to detect such changes. The choice of GCR for a giv...

A standard color space, sRGB, has been widely used for reproducing the accurate color in the internet system. However, this color is accurate only under the sRGB reference viewing environment. In practice, the customers viewing environments are not always standard conditions. It is known that the multispectral color reproduction can be used to obtain highly accurate colors which are independent...

Web enabled color smoothing schemes, employed in applications such as VRML, cooperative design tools and online 3D game rendering engines, rely on constant color triangulation. This artifact is unsuitable for high quality medical and microelectronic images. For convex polygonal image-subsets Wachspress’ rational polynomial shape functions provide the best continuous coloring. It is available on...
