This paper presents a new method that utilizes the technologies of image processing and computer vision. Firstly, the projected areas of the pig’s image captured directly from top view are computed. Secondly, the heights are obtained from side view. Then the pig’s weight is estimated by the projected areas and heights. By comparing with the real weight, the mean relative error is 3.2%. The expe...

Ixodes pacificus, particularly the nymphal life stage, is the primary vector to humans of the Lyme disease agent Borrelia burgdorferi in California. During 2004, we collected I. pacificus nymphs from 78 woodland sites in ecologically diverse Mendocino County, which has a moderately high incidence of Lyme disease. Within this county, nymphal density was elevated in forested areas with a growing ...

physical properties of fruits and vegetables are the subject of many researches because of its importance in designing of agricultural machinery. banana fruit is one of important fruit. in this study some physical properties of banana fruit (cavendish variety) were determined. properties which were measured included weight of whole fruit peel and pulp weight, dimensions, surface area and projec...

some physical attributes of two common types of iranian garlic cloves (white and pink) were identified and compared. a machine vision system was used to determine three di-mensions and both major and minor projected areas of garlic cloves at a moisture content of 42.4% w. b. the geometric mean diameter and sphericity were calculated, as well as the unit mass and volume of cloves were measured. ...

Given their physiological requirements, limited dispersal abilities, and hydrologically sensitive habitats, amphibians are likely to be highly sensitive to future climatic changes. We used three approaches to map areas in the western hemisphere where amphibians are particularly likely to be affected by climate change. First, we used bioclimatic models to project potential climate-driven shifts ...

I review the sensitivities achieved by and projected for fixed-target charm experiments in CP violation, flavor-changing neutral-current and lepton-number-violating decays, and mixing, and I describe the Charm2000 experiment intended to run at Fermilab in the Year ≈2000. If approved, Charm2000 will in many of these areas exceed the sensitivities projected for a Tau/Charm Factory, but the Tau/Ch...

In this paper, a novel technique for the segmentation and tracking of moving objects is proposed. The proposed scheme extracts moving objects based on both motion and spatial information. Initially, an intra-frame segmentation is performed using a morphological segmentation algorithm. After this, the video object areas are merged according to their motions based on a new criterion. When differe...
