Direct estimation of cardiac ventricular volumes has become increasingly popular and important in cardiac function analysis due to its effectiveness and efficiency by avoiding an intermediate segmentation step. However, existing methods rely on either intensive user inputs or problematic assumptions. To realize the full capacities of direct estimation, this paper presents a general, fully learn...
In spite of the existing reports on behavioural and biochemical changes related to the cerebellum due to noise stress, not much is known about the effect of noise stress on the neuronal changes in the cerebellum. The present study aims at investigating the effects from one week noise exposure on granule cell number and Purkinje cell volume within the neonate rat cerebellum.15-day-old male Wista...
Cardiac electrical impedance tomography (EIT) signals are affected by myocardial motion. The feasibility of stroke volume estimation using such signals is thus questionable. Results based on a dynamic model show that myocardial motion indeed affects but does not compromise stroke volume estimation.
Computer vision has been introduced to estimate calories from food images. But current food image datasets dont contain volume and mass records of foods, which leads to an incomplete calorie estimation. In this paper, we present a novel food image dataset with volume and mass records of foods, and a deep learning method for food detection, to make a complete calorie estimation. Our dataset incl...
Total tree volume estimation is an integral part of forest growth and yield forecasting. Complex formulae are used to estimate bole volume by section, based on relationships proposed by Huber, Smalian and Newton. All these relationships require many measurements of bole diameters at certain heights that are difficult to obtain on standing trees especially when diameter measurements have to be t...
Abstract—The objective of this paper is to investigate the volume scattering for the vegetation parameter estimation of Polarimetric Interferometric Synthetic Aperture Radar (Pol-InSAR). Firstly the models for describing the volume scattering are derived from the Pol-InSAR imaging geometry and volume scattering characteristics. The interferometric properties of volume scattering as well as the ...
