This paper proposes a new representation for color texture using a set of multiscale illuminant invariant features. The approach was specifically developed to investigate the feasibility of using machine vision to automatically monitor populations of animal species in ecologically sensitive regions, such as the Amazon Forest. The approach uses a combination of Finlayson's (1994) color angle ide...

soil hydraulic properties such as soil water characteristic curve are necessary prerequisite for modeling water movement and solute transport. direct methods of estimating these hydraulic properties are time consuming and costly. indirect methods, such as pedotransfer functions, estimate the hydraulic parameters using easy-to-measure soil properties like particle size distributions, bulk densit...

In this paper, a fast search algorithm for mean pyramids vector quantization by using Hadamard transform of the vector is proposed. The algorithm uses mean pyramids of the vectors and codewords after applying Hadamard transform and one elimination criterion based on deviation characteristic values in the Hadamard transform domain to eliminate unlikely codewords. Our algorithm has the same quali...

milk-based espresso coffee is one of the most popular beverages. foam is an essential quality characteristic for this beverage. foam formation and stability is mainly related to the milk composition. in this study the influence of three different concentrations of xanthan gum (0.05, 0.1 and 0.2 g dm-3) and three different temperatures (50, 60 and 70 °c) on foam stability were examined and exper...
