Log polar transform is not only a mathematical description of the retino-cortical mapping of human vision system, but also a vital algorithm of space-variant resolution theory. The obverse transform algorithm leads to pixel discreteness in the fovea area. Aiming at solving this problem, the inverse log polar transform algorithm based on grey weight value of neighbor pixels is presented. According...
Many species of parasitoids can increase their reproduction through feeding on supplemental sugar sources. We evaluated the longevity both with and without hosts and progeny production of a uniparental strain of Meteorus pulchricornis by varying concentration of the sugar solution and feeding frequency. A 1:1:1 sucrose–glucose–fructose-mixture was tested in a range of concentrations (0–70% (w/v))...
