Her Whorl

Delving into the Whorl of Flower Segmentation

We describe an algorithm for automatically segmenting flowers in colour photographs. This is a challenging problem because of the sheer variety of flower classes, the intra-class variability, the variation within a particular flower, and the variability of imaging conditions – lighting, pose, foreshortening etc. The method couples two models – a colour model for foreground and background, and a...

Delving deeper into the whorl of flower segmentation

We describe an algorithm for automatically segmenting flowers in colour photographs. This is a challenging problem because of the sheer variety of flower classes, the variability within a class and within a particular flower, and the variability of the imaging conditions – lighting, pose, foreshortening, etc. The method couples two models – a colour model for foreground and background, and a li...

Laterality in children: cerebellar dominance, handedness, footedness and hair whorl

The purpose of our study was to ascertain the degree of correlation between handedness and physiological neocerebellar extinction syndrome demonstrable on the side contra lateral to the dominant upper extremity. Using the Edinburgh questionnaire and other tests for “handedness”, we examined 221 healthy 9–11-year old schoolchildren for handuse preference. To test their handedness the following 6...

The genetic basis of hair whorl, handedness, and other phenotypes.

Evidence is presented that RHD, RHCE, and other RH genes, may be interesting candidates to consider when searching for the genetic basis of hair whorl rotation (i.e., clockwise or counterclockwise), handedness (i.e., right handed, left handed or ambidextrous), speech laterality (i.e., right brained or left brained), speech dyslexia (e.g., stuttering), sexual orientation (i.e., heterosexual, hom...
