Corner detection is a fundamental step in image processing, and it takes an important role in target tracking, image stitching and three-dimension reconstruction. Harris algorithm is widely used in corner detection for simple calculation and its detection result is not affected by image rotation and light intensity changes. Harris algorithm uses integral differential mask to extract the image g...

Morbidity studies by Logan (1960) have also shown a similar, though less steep, social class gradient. These class differences are generally thought to be due to adverse factors associated with life in the lower social classes (Registrar General, 1938, 1958b; Vernon, 1939; Goodman, Lane, and Rampling 1953; Pemberton, 1953; Lane, 1954; Fletcher, 1956; Stuart-Harris and Hanley, 1957). It is also ...

A φ-irreducible and aperiodic Markov chain with stationary probability distribution will converge to its stationary distribution from almost all starting points. The property of Harris recurrence allows us to replace “almost all” by “all,” which is potentially important when running Markov chain Monte Carlo algorithms. Full-dimensional Metropolis–Hastings algorithms are known to be Harris recur...

In 1841, T. W. Harris published "A Report on the Insects of Massachusetts, Injurious to Vegetation," a seminal work in North American Entomology and one of the first New World publications to describe Lepidoptera species. Although appearing in several subsequent editions, the eight family-group names proposed by Harris were largely overlooked. In summarizing Harris' family-group names, we show ...

According to the rotational invariance of Harris corner detector and the robustness of Sift descriptor. An improved Harris-Sift corner descriptor was proposed. At first, the algorithm given multi-scale strategy to Harris corner, improved corner counting method and removed redundant points at the same time, then, the corner was directly applied to low-pass Gaussian filter image. Based on the his...

Harris (2006) recently proposed a new elemental model of the processes involved in associative learning. Although Harris explicated all relevant mathematical and conceptual details of the model in his article, implementing a computer simulation of his model requires considerable programming expertise and work. We therefore present the Harris model simulator (HMS), a MATLAB simulator of Harris's...

A happy New Year!?even though it has had a very cold start. Our thoughts have been with those of you, who besides ourselves in London, have had to battle with the bitter weather. In particular we have thought of our 35 residents at Parnham (none younger than 70 and one in her 90s) and the staff, who have had a particularly difficult time in Dorset. Dr. Noel Harris draws attention in a special a...
