Auto-exposure(AE) control automatically calculates and adjusts the exposure of the tone of the subject to the midtone of the photograph. In the case of real-time performance, this is usually controlled by the sensor gain for consecutive input images. However, unsuitable sensor gain control methods invariably cause oscillation of the average luminance values for continuous input images, resultin...

Abstract Canopy nitrogen content (CNC, kg/ha) provides crucial information for site-specific crop fertilization and the usability of Sentinel-2 (S2) satellite data CNC monitoring at high levels in managed agricultural fields is still underexplored. Winter wheat samples were collected France Belgium 2017 (n = 126) 2018 18), analysed S2-spectra extracted sample locations. A comparison three estab...

A high sensitivity Cardiac SPECT system using curved crystals with pinhole collimation was proposed previously (Dey, IEEE TNS 2012, Bhusal et al, Med. Phys. 2019). Here, we hypothesize that a curvature hemi-ellipsoid detector results in measurable differences light distribution from events at different depths the crystal. This tested by analyzing scintillation Monte-Carlo (Geant4) and evaluatio...

Multimedia algorithms in their majority consist of regular repetitive loop constructs. In this paper, a novel control unit design for implementing such loop intensive algorithms is described. The proposed architecture, termed as zero-overhead loop controller (ZOLC) exploits the regularity of computations, which is a common characteristic of multimedia algorithms in order to efficiently support ...

In this paper we consider the k-clustering problem for n points in the d-dimensional space, motivated from the problem of computing a color lookup table for frame bu er display, and that of compressing two-dimensional image data. Using the technique of computational geometry, this clustering problem is investigated in a uni ed manner.

Abstract The resolution of cameras is increasing, and speedup various image processing required to accompany this increase. A simple way acceleration the at low then upsampling result. Moreover, when we can use an additional high-resolution as guidance formation for upsampling, upsample results more accurately. We propose approach accelerate by downsampling joint upsampling. This paper utilizes...
