An important area of automatic industrial inspection that has been largely overlooked by the recent wave of research in machine vision applications is the detection of defects in textured surfaces. In this paper, we present di erent algorithms for the detection of surface abnormalities both in the chromatic and structural properties of random textures. We present very promising results on the d...

Both improving agricultural soil productivity and maintaining its quality are now the focal points of ongoing research in agriculture. The purpose this is to examine soil's health, order do so, a survey was carried out which physicochemical parameters macronutrients soils from two districts state Punjab (Hoshiarpur Nawanshahr) were analyzed. Around 40 composite samples taken 0 15 cm depth criti...

The purpose of this work is to analyse what happens to the surface information when the image resolution is modi ed. We deduce how the surface texture appears if seen from di erent distances. Using Colour Photometric Stereo a method for predicting how surface texture looks like when changing the distance of the camera is presented. We use this technique on the recognition of textures seen from ...

This work focuses on the automatic monitoring of the natural environment using images of animals. An unsupervised 3D colour texture segmentation and recognition algorithm is developed and applied in the recognition of natural patterns (monkeys) in outdoor image scenes (Amazon Forest). We present an unsupervised segmentation algorithm, which uses 3D Graph-theoretical clustering for colour images...

-This paper describes initial results of a 3D field topology analysis for automating colour transfer function design aiming at comprehensible volume rendering. Computed tomography (CT) scanners measure the linear xray radio density attenuation values of body tissues in Hounsfield units (HU). Many alternative colour maps have little additional diagnostic or intuitive value relative to grayscale....

In this paper a method that facilitates an iconic query of an image/video database is presented. A query object is characterised by colour and texture properties. A feed-forward neural network is then trained on these features using the conjugate gradient-descent algorithm. The same characteristics are computed locally for the database images. The trained neural network is then used to test for...

Full fat flaxseed flour was supplemented with wheat flour @ 5, 10, 15, 20,25 and 30%. Cookies were prepared from composite flours. Cookies prepared without flaxseed flour were kept as control. The mean quality score of the cookies decreased with the increase in the level of the flaxseed flour supplementation. Colour and crispiness of the cookies showed a declining trend as compared to flavour a...

A perceptual approach to generating features for use in indexing and retrieving images is described. Salient regions that immediately attract the eye are colour (textured) regions that usually dominate an image. Features derived from these will allow search for images that are similar perceptually. We compute colour features and Gabor colour texture features on regions identified from a coarse ...

Aims In bakery products, quality attributes of the crust such as crispy texture and colour and of the crumb as softness and springiness are important attributes for consumer’s perception. These attributes mainly set up during the baking stage and are influenced by the baking conditions (oven temperature, steam injection...). Many physical and chemical changes occur to lead to a porous structure...

This work deals with changes in functional and sensory properties during freezing and frozen storage of Atlantic mackerel pre-treated by high hydrostatic pressure processing (HPP)....
