At the beginning of each game, or in order to move up a level, players see magnified pictures of real tumours and are asked some simple questions about what they can see, based on shape, colour and brightness.
Using color fundus image information, methods based on shape, colour and texture features, [ 11] local contrast of the red-channel [ 14] or red reflex [ 3, 9- 13, 13- 15], have great potential to classify the retinal arteries.
Another part of her PhD work at Leeds is to detect carried objects based on shape and colour.
There is a visible difference between the centre and edges of each colony, but the colonies could otherwise not be visually distinguished based on shape and colour.
For example, chimpanzees can be trained to discriminate between stimuli based on shape if the stimuli are presented on white background and by colour if the stimuli are presented on a black background [13].
Colonial morphology was done by examining and grouping the colonies based on the shape, colour, border, texture, and general appearance of the colonies of bacteria on each plate.
A machine learning method was then used to label each superpixel as either tumour or non-tumour based on its colour, shape and visual texture, as well as similar properties from nearby superpixels.
Individuals were classified as yearlings (i.e. second year birds) or older birds (i.e. after-second year birds) based on the shape and colour of their primary coverts, the presence of a moult limit, and the shape and colour of their tail feathers [ 25].
All specimens were live-sorted into gross morphospecies using a standard dissecting microscope (20x magnification) in a field laboratory setting based on colour, size, shape, collection date, and collection site.
We immediately separated the ostracods into morphospecies based on site, colour, size, and shape using a light box and a standard dissecting microscope in a field laboratory setting, and preserved them in ethanol.
These automated scanning microscopes and image analysis systems consist of a slide loader, camera, computer and software for the detection and classification of cells of interest, based on particular colour, intensity, size, pattern and shape.
