The use of analogies to physical phenomena is an exciting paradigm in computer vision that allows unorthodox approaches to feature extraction, creating new techniques with unique properties. A technique known as the “image ray transform” has been developed based upon an analogy to the propagation of light as rays. The transform analogises an image...
Extraction of blood vessels within the retina is an important task that can help in detecting a number of diseases, including diabetic retinopathy. Current techniques achieve good, but not perfect performance and this suggests that improved preprocessing may be needed. The image ray transform is a method to highlight tubular features (such as blood...
The ear is a maturing biometric with qualities that give it superiority over other biometrics in a number of situations; in particular the ear is relatively immune to variation due to ageing. Successful ear biometrics rely upon a well enrolled dataset, with ears normalised for position, scale and rotation. We present a novel ear enrolment technique...
Physical analogies are an exciting paradigm for creating techniques for image feature extraction. A transform using an analogy to light rays has been developed for the detection of circular and tubular features. It uses a 2D ray tracing algorithm to follow rays through an image, interacting at a low level, to emphasise higher level features. It has...
Video and computer games controls and controllers have gone through a large amount of change recently. The intro-duction of new, more immersive control technologies such as motion sensing and touchscreens into the commercial games market has and will change the design of games. This pa-per looks at how games have spurred on the development of contr...

... Some of these devices have used this methods of input as gestures to enable good user experience: like dragging for changing the website pages, zooming options on image viewer and many others features. Mobile game developers can add several buttons, design it positions and size of any buttons at the screen of smartphone. A. H. Cummings [7] told, one of the purposes for game interface is the ability to do something normally and have your action reflected in the game world by your game character. Computer vision technology is used to analyze images of the player's movements and transform it into movement in the game world environment. ...
... It has achieved robust results in background clutter, viewing angle, and occlusion. Cummings et al. [50] used the image ray transformation, based upon an analogy to light rays, to detect an image's ears. is transformation can highlight tubular structures like the helix of the ear and spectacle frames. By exploiting the elliptical shape of the helix, this method segmented the ear into regions and achieved a detection rate of 99.6% using the XM2VTS database. ...

... Ansari and Gupta [7] proposed a method that also detects ears in image space by detecting edges and segregating them into concave and convex edges, thus finding the outer helix region. Cummings et al. [17] detect ears in the images by modelling light rays and finding the helix regions. Other methods work in both image and depth space. ...
... Retinal blood vessels segmentation considered to be useful procedure for several pathological states detection [9]. Several methods have been proposed in the literature for segmenting blood vessels from color fundus images been done including wavelet transforms [7], hybrid filtering [10], matched filter [11], [12], radon transform and morphological reconstruction [13], as well as image ray transform [14] and by radon transform and morphological reconstruction. All these algorithms are affected in their accuracy by some pathological elements like microaneurysms and hemorrhages as they appear with the same color of blood vessels, also the presence of noise, the contrast, vessels different widths and the brightness [15]. ...
