This study observed the yield response to nitrogenous fertilizer for a popular Boro rice variety BRRI dhan29 under silty loam texture soil with satisfactory organic matter (2.96%). Sequential elevated doses of nitrogen (N0, N70, N80, N90, N100, and N110 kg ha-1) along recommended phosphorus (P), potassium (K), Sulphur (S) significantly increased grain […]

In the field of image processing, texture features and color are fundamental visual cue with complementary roles. They used in many applications a large variety areas such as quality control, content-based retrieval, remote sensing, industrial inspection, surface object recognition, medical analysis. For this purpose, number algorithms have been proposed for feature extraction. Some them dedica...

1.1. QCoh on a stack. We know that QCoh forms a stack, i.e., sheaf of groupoids, over Schfpqc(S) for any scheme S. Thus if we have an fpqc sheaf of groupoids X over S, we can define QCoh(X ) as maps of sheaves X → QCoh on Schfpqc(S). By 2-Yoneda, this definition agrees with the usual notion of quasicoherent sheaves if X is a scheme. For various other (usually equivalent) definitions in the case...

This case study presents an automated method for digitizing complex free-form surfaces. Hardware and software components developed at the Fraunhofer IFF allow generating texturized virtual models from physical objects. Both the 3-D geometry and the surface texture (color information) are measured with high spatial resolution. The method can be applied to a variety of object measurements, for in...

Automated systems for understanding display boards are finding many applications useful in guiding tourists, assisting visually challenged and also in providing location aware information. Such systems require an automated method to detect and extract text prior to further image analysis. In this paper, a methodology to detect and extract text regions from low resolution natural scene images is...

A major determinant of human texture segregation and discrimination is the orientational content of the stimuli ~used. We have investigated the ability of observers to resolve features defined in the orientation domain in a variety of textures. It was found that features had to be separated by at least 13 deg for subjects to discriminate orientationally bimodal textures from same-variance unimo...

This paper proposes a new object-based approach to similar image retrieval. First the salient regions of an image are detected by using a novel segmentation method based on a multi-scale inhomogeneous diffusion model applied to color and texture features. Each detected region is then represented by a feature vector composed from the characteristic color, texture and shape features of a region w...

The avocado is a tropical fruit whose nutritional value is due mainly to its high lipid content. The aim of this work was to evaluate the rehydration of freeze-dried avocado (variety Collinson) powder and slices. The rehydration kinetics was determined using an experimental apparatus that monitored the volume of water absorbed by the sample with the time. Peleg and Weibull equations were used t...
