Comparison of Predicted Values from Various Colour-difference Formulae with Perceived Chroma-differences

Comparison of Hardness Values of Various specimens with different geometries and material properties after ECAP

Nowadays, equal channel angular pressing, known as the ECAP process, is one of the most popular methods for manufacturing ultra-fine grained (UFG) materials. In this paper, Ecap process has been carried out on pure copper and 6012 aluminum alloy up to six passes by route . Principal attention was paid to the influence of parameters such as diameter, material, and the height of billet on mechani...

Quantifying Plant Colour and Colour Difference as Perceived by Humans Using Digital Images

Human perception of plant leaf and flower colour can influence species management. Colour and colour contrast may influence the detectability of invasive or rare species during surveys. Quantitative, repeatable measures of plant colour are required for comparison across studies and generalisation across species. We present a standard method for measuring plant leaf and flower colour traits usin...

Chroma and Contrast Features Based Image Difference Measure in Various Scales

An image difference structure is created that include of image regularization, feature derivation, and feature grouping. Based on this structure image difference measure is created by selecting exact implementations for each of the steps. An image difference prediction is then calculated using image difference features (IDFs) that are derived from the images. The input images are then regulariz...
