Title: Colour contrast enhancement of medical images by non-linear colour mapping
Inventor: PIOTR KUCHNIO
IPC: G06T11/00
Filed: 2015-09-02
Abstract: An image enhancement system and method for enhancing medical images from a surgical imaging system. Each image pixel has a value in a first three-dimensional colour space. A mapping of values in a subset of the first colour space is calculated to map each colour point in the subset to an enhanced value. The mapping is calculated by selecting a reference point in the subset and, for each colour point in the subset, mapping the colour point to a modified colour value offset from the reference point by the modified colour point vector that has the same direction as the colour point vector extending from the reference point to the colour point, but a greater magnitude. The mapping is applied to the pixel values in the medical image falling in the subset to produce an enhanced image.

Title: Fibre flattening
Inventor: CLAUDIO SANTONI
IPC: B29C70/56
Filed: 2018-03-29
Abstract: A method of forming a fibre article, comprises providing a contoured former and locating a fibre preform between first and second diaphragms. Vacuum is applied between the diaphragms which are then displaced bringing the second diaphragm into contact with prominences 14’, 15’on either side of a concavity of the former whilst it does not fully contact the concavity. Then vacuum is applied between the second diaphragm and the former bringing the second diaphragm into conformity with the forming surface and the preform is set to shape in its configuration. The preform comprises inextensible fibres extending linearly between the prominences. As the diaphragms are stretched into the concavity they tend to place the inextensible fibres under tension which helps to reduce the amount of the preform between the prominences to limit the formation of folds or wrinkles. The inextensible fibres may be in the form of a layer 51 which, or has extensions 53 which, extend/s outwardly of the prominences 14’, 15’. Layer 15 may be one of several making-up the preform. Also disclosed is a first diaphragm which is thinner and/or more elastic than a second diaphragm to provide good conformity of a preform to a former.
