Color combination criteria in Le Corbusier's Purist architecture based on Salubraclaviersfrom 1931

Evaluating the 1931 CIE Color Matching Functions

The use of colorimetry within industry has grown extensively in the last few decades. Central to many of today’s instruments is the work of the CIE system, established in 1931. Many have questioned the validity of the assumptions made by Wright (1928-29) and Guild (1931), some suggesting that the 1931 color matching functions are not the best representation of the human visual systems’ cone res...

A New Method for Encryption of Color Images based on Combination of Chaotic Systems

This paper presents a new method for encryption of color images based on a combination of chaotic systems, which makes the image encryption more efficient and robust. The proposed algorithm generated three series of data, ranged between 0 and 255, using a chaotic Chen system. Another Chen system was then started with different initial values, which were converted to three series of numbers from...

Color Image Retrieval Based on Weighted DCT Spatial Combination Histogram

Color histograms are the most commonly used features for image retrieval due to the good attributes of image translation and rotation invariance. However the traditional color histogram features are usually short of spatial structural information which may cause error retrieval results. This paper presents a color image retrieval method based on Weighted DCT Spatial Combination Histogram (WDSCH...

E-Service Architecture Selection Based on Multi-criteria Optimization

The selection of the most acceptable architecture of e-services system is very important issue. One and the same e-service can be designed using different alternative architectures. Each system has different execution indices that are very important for the e-services clients and providers. This article shows solutions for compromise or the most acceptable selection of the architecture of e-ser...
