Abstract: A method of obtaining a measurement of the extent of telangectasia in an area of skin is disclosed. Initially (S3-1) an image of an area of skin (2) to be analyzed is obtained. The obtained image is then processed (S3-2-S3-3) to determine blood distribution data indicative of the distribution of blood in an imaged area of skin. This blood distribution data is then converted (S3-5) using a Discrete Fourier Transform and the converted blood distribution data is then processed to obtain a measurement of the extent features in a determined distribution of blood correspond to structures of a predetermined size. The obtained measurement of the extent of telangectasia can then be combined (s3-6) with other measurements of the effects of photo-damage such as measurements of melanin disorder and collagen degradation to obtain a measurement of the extent of photo-damage.

Abstract: An image of an individual (2) is obtained using a digital camera (1). The image data is then processed by ratio determination module (10) and an image conversion module (12) to analyze the image and determine data representative of the distribution of blood and melanin in the skin of the imaged individual. This chromophore distribution data is then processed by an image generation module (18) which generates an image representative of the expected appearance of epithelial tissue having the determined distribution of chromophores where the epithelial tissue is under fixed illumination and has a flat spatial geometry and where all the identified melanin is present solely in the epidermis.

Abstract: An image of an individual (2) is obtained via a digital camera (1). The RGB image data is then processed to derive from the image data data representative of the distribution of chromophores resulting in the appearance of the individual (2). A calculated chromophore distribution is then utilised to derive a revised chromophore distribution representing the effect of the desired cosmetic or surgical intervention or medical condition. This chromophore distribution is then processed to generate an output image (34) illustrating the expected result of that intervention. The generated image (34) can be displayed simultaneously with an original image (33) so that the extent of expected improvement can be determined.

Abstract: A camera (1) is provided which is operable to obtain a RGB and infra-red image of an area of illuminated skin (2). The obtained image is then passed to a computer (8) which determines the manner in which light returned by points on the surface of the illuminated area of skin (2) appearing in the obtained image varies due to variations in lighting intensity and surface geometry. The infra-red channel of the obtained image is then normalized on the basis of the determined variations and a measurement of collagen thickness can then be determined utilizing the processed infra-red channel of the obtained image. The determination of variations in intensities of light returned by points on the surface of the illuminated area of skin (2) can be achieved by processing an obtained image to generate a 3-D model of the surface being imaged and using the 3-D model to select and process pre-stored lighting level data.

Abstract: Among various methods, apparatuses, and media, recording media having executable instructions are provided for measuring skin surface texture. One such execution of instructions can process an obtained first measurement of light utilising a model of the interactions of light with chromophores present in skin to determine variations in returned light levels arising due to variations in levels of illumination. Execution of such instructions can utilise a difference between the obtained first, and an obtained second measurement of light returned by an illuminated area of the skin and determined variations in returned light levels arising due to variations in levels of illumination, to obtain a measurement of the surface texture of the illuminated area of the skin.

Abstract: Among various methods, apparatuses, and media, a number of methods are provided for measuring skin surface texture. One such method includes illuminating an area of skin with polarized light, and obtaining a measurement of light returned by the illuminated area of skin in a first and a second waveband. The method includes processing the measurement of light in the first waveband to determine an estimated expected level of light in the second waveband returned by the illuminated area of skin utilising a model of the interaction of light with at least one chromophore in the skin. A measurement of the surface texture of the imaged illuminated area of skin can be determined on the basis of a difference between the estimated and actual levels of light in said second waveband returned by the illuminated area of skin.
