This paper presents a new algorithm for locating the boundaries of textured regions (both step changes and outliers) using a robust estimator. Previous robust image lters perform poorly on binary images, blur edges, round corners, and run slowly. I avoid artifacts on binary images by modelling them as continuous and interpolating values. Information is combined directly between non-adjacent loc...

In order to study large variations or fluctuations of finite or infinite sequences (time series), we bring to light a 1868 paper of Crofton and the (Cauchy-)Crofton theorem. After surveying occurrences of this result in the literature, we introduce the inconstancy of a sequence and we show why it seems more pertinent than other criteria for measuring its variational complexity. We also compute ...

To promote the use of oral rehydration therapy (ORT), a training programme was launched by The Pakistan National Programme for Control of Diarrhoeal Disease (CDD) by establishing the Diarrhoea Training Units (DTUs). Physicians trained at DTU were designated to establish functioning oral rehydration therapy (ORT) corners at their health centres and train health workers in delivery of facilities ...

Video panoramic image stitching is extremely time-consuming among other challenges. We present a new algorithm: (i) Improved, self-adaptive selection of Harris corners. The successful stitching relies heavily on the accuracy of corner selection. We fragment each image into numerous regions and select corners within each region according to the normalized variance of region grayscales. Such a se...

The Southwestern U.S. has been in a megadrought for the past two decades, stressing vegetation across region and leading to poor forage conditions on rangelands. How human-induced climate change affected air temperatures atmospheric evaporative demand greater Four Corners of Southwest, what have corresponding impacts vegetative productivity? We address this question via multi-step detection att...
