A novel colour model for colour detection

Colour detection plays an important role for many computer vision-based applications. However, most existing colour detection methods tend to be environment dependent since slight changes of environmental factors such as illumination or shadowing effects could greatly reduce their performances. In this paper, a new colour model is introduced to allow enhanced colour detection from images, even with significantly different lighting conditions and image qualities. The proposed colour model is called the HPBr colour model. It is converted from the RGB colour model and it consists of three colour components, namely, hue (H), purity (P) and brightness (Br). This colour model can be represented in three different geometric shapes: diamond, sphere and cylinder. To assess the effectiveness of the model, two different colour detection methods have been applied onto benchmark images. Experimental results from both methods confirmed that the proposed colour model produced the best colour detection results among existing models.     

Developing a custom colour target for artwork imaging

Abstract

When characterising digital camera for capturing art paintings, the standard targets are often used, resulting in unacceptable differences in reproducing some special colours, so additional time must be spent for visual editing and colour adjusting in various software applications. To avoid the need for excessive colour editing, and to improve workflow efficiency and colour accuracy, the special colour reference target for digital camera characterisation was developed, applied and tested in these research. The object of digitalisation was paintings made with gouache paint, so two custom gouache reference targets with different numbers of colour samples (named CGRT24 and CGRT96) were created for digital camera colour characterisation. The main criteria for construction of targets were defined, as the optimal studio conditions for digital image capture of art paintings. By analysing the results gained with profiles testing, it was established that the errors in colour reproduction, which appear when using the standard targets (GretagMacbeth ColorChecker and ColorChecker DC) was decreased when using the developed CGRT targets for digital camera characterisation. Also, it was found out that the larger number of colour samples on target does not guarantee the more accurate camera profile. The results show that the colorimetric properties of colour samples are more important than the number of samples and proves that there is a benefit of developing the custom target tailored to the specific need.     

Image processing-based method for glass tiles colour matching

Abstract

Furniture glass tiles are increasingly used for covering walls and facades or for conferring fashionable aesthetical properties to buildings. Companies that produce furniture glass tiles of a desired colour are devoted to performing a colour comparison between the manufactured glass tiles and the ones desired by a customer, or provided by a catalogue. Still today, such a comparison, known as ‘colour matching’, is mainly performed by company experts by means of a visual inspection, thus leading to a subjective and qualitative colour assessment. A number of methods for colour matching have been afforded in the literature in several industrial fields such as textile, plastics or food; unfortunately, to the best of author’s knowledge, no practical method for glass tiles colour matching has been devised until today. The present work provides an image processing-based method capable of carrying out non-patterned glass tiles colour matching. The method is devised using an appositely developed hardware so as to extract a series of statistical data from scanned images of 10 mm sized glass tiles and, on the basis of the definition of two novel colour distance formulas, endows with colour matching. The achieved colour matching performance agrees in 91% of tests with expert-performed colour classification. The provided formulas are meant to be of general usage for assessing glass tiles colour matching.     

Mechanism of variable structural colour in the neon tetra: quantitative evaluation of the Venetian blind model

The structural colour of the neon tetra is distinguishable from those of, e.g., butterfly wings and bird feathers, because it can change in response to the light intensity of the surrounding environment. This fact clearly indicates the variability of the colour-producing microstructures. It has been known that an iridophore of the neon tetra contains a few stacks of periodically arranged light-reflecting platelets, which can cause multilayer optical interference phenomena. As a mechanism of the colour variability, the Venetian blind model has been proposed, in which the light-reflecting platelets are assumed to be tilted during colour change, resulting in a variation in the spacing between the platelets. In order to quantitatively evaluate the validity of this model, we have performed a detailed optical study of a single stack of platelets inside an iridophore. In particular, we have prepared a new optical system that can simultaneously measure both the spectrum and direction of the reflected light, which are expected to be closely related to each other in the Venetian blind model. The experimental results and detailed analysis are found to quantitatively verify the model.     

Influence of Colour Couplers on the Adsorption of Spectral Sensitizing Agents

The spectral sensitivity of a spectrally sensitized emulsion is in many cases altered by the addition of colour couplers. This alteration is mainly due to a partial desorption of the sensitizing agent. Two possible cases of interaction between the colour coupler and the sensitizer hare been studied.

1. The colour coupler itself is not adsorbed on the surface of the silver halide but forms micelles in the gelatin phase. These micelles act as dissolving agents and desorb the sensitizing agent from the surface of the silver halide crystals. The isotherm, giving the amount of sensitizer solubilised by the colour coupler as a function of the amount still adsorbed on the silver halide crystals, has two different saturation levels.

2. The colour coupler is adsorbed In this case the colour coupler and the sensitizing agent scarcely disturb the adsorption of each other A multilayer adsorption is believed to take place

Three fringe photoelasticity - use of colour image processing hardware to automate ordering of isochromatics

The early application of digital image processing (DIP) technique to automate photoelastic analysis is based on black and white (B & W) image processing systems. The various methodologies reported can be traced to rely upon one or several features of a B &W DIP system. With the advancements in computer technology, nowadays colour image processing systems are available at affordable prices. A systematic study has been carried out on how to use the red green blue (RGB) value recorded using a colour image processing system for determining fringe orders up to 3 in a fringe field. The study has revealed that instead of directly using RGB values corresponding to a dark field image, if the difference of RGB values between bright anddarkfield images is used, the number of noise points is less. Experiments have been carried out for several arbitrary lines in a circular disk under diametral compression and the results are found to be good.     

Colour filter array demosaicking over compression through modified grey wolf optimization technique

The three colour intensity values red, green and blue are acquired in a single pixel on using a multi-sensor camera. The single sensor camera uses the colour filter array to grab only one intensity value in a pixel location. The reconstruction of the so-called raw image into a full colour image is called demosaicking. This paper proposes a novel framework for effective demosaicking combined with the compression over the input image using a modified grey wolf optimization algorithm. The demosaicking process is efficient in applying the Modified Grey Wolf Optimized wavelet compression to optimally select the coefficients and Modified Huffman Coding technique to the image before demosaicking. The proposed technique is evaluated by the Peak Signal Noise Ratio, Structural Similarity Index Measure and Feature Similarity Index Measure values and has proved both subjectively and objectively to have better demosaicking results.
