摘要： Medical image data is analysed to produce a biomarker. The data is filtered with a plurality of band-pass filters each having a different bandwidth. A texture parameter is then determined from the filtered data from each filter and the biomarker is determined as at a ratio of the texture parameters. When the biomarker is obtained from a CT image of a liver, it can be predictive of poor survival, disease extent and liver physiology of a patient following resection of colorectal cancer. When obtained from a mammographic image, the biomarker can be indicative of cancer invasion and receptor status within mammographic abnormalities. When obtained from a CT image of a lung nodule, the biomarker can be predictive of tumour stage (or grading) and tumour metabolism of a patient with non-small cell lung carcinoma (lung cancer).

摘要： The present invention provides a method of computer analysis of a data set representing an image to extract a texture based measure therefrom, said image including a multiplicative bias in intensity within the image of unknown magnitude, the method comprising applying to said data set a bank of texture extracting filters, such that said filters are chosen from filters that are invariant to the presence of a multiplicative bias field. By providing such a method, rather than attempting to correct the bias field before extraction of a texture based-biomarker, a texture-based biomarker that is bias field invariant is extracted. This makes correction of the bias field unnecessary.

摘要： An image analysis unit of an image processing apparatus acquires a distribution condition of feature points in an entire input image and in each of a plurality of small regions in the input image. A target point number setting unit sets a target point number for each small region based on the distribution condition of feature points in the entire input image. An expected point number setting unit sets an expected point number for each small region based on the distribution condition of feature points in the small region. A comparison unit compares the target point number and the expected point number. A sensitivity setting unit sets detection sensitivity based on the comparison result. A feature point detection unit performs feature point detection according to the detection sensitivity.

摘要： A method of determining whether a biometric object is part of a live individual is described. In one such method, image information is acquired from the biometric object by using a sensor, such as an ultrasonic sensor. The image information may be analyzed in at least two analysis stages. One of the analysis stages may be a temporal analysis stage that analyzes changes in the image information obtained during a time period throughout which the biometric object was continuously available to the sensor. For example, a dead/alive stage may analyze differences between image information taken at two different times in order to identify changes from one time to the next. Other stages may focus on aspects of a particular image information set, rather than seeking to assess changes over time. These other stages seek to determine whether an image information set exhibits characteristics similar to those of a live biometric object.

摘要： Relightable free-viewpoint rendering allows a novel view of a scene to be rendered and relit based on multiple views of the scene from multiple camera viewpoints. An initial texture can be segmented into materials and an initial coarse colour estimate is determined for each material. Scene geometry is estimated from the captured views of the scene and is used to scale the initial coarse colour estimates relative to each other such that the different materials appear to be lit with a similar irradiance. In this way, a global irradiance function is estimated describing the scene illumination. This provides a starting point for a colour estimate and shading estimate extraction. The shading estimate can be used to fit surface normals to the global irradiance function. The set of surface normals and the colour estimate are stored for subsequent use to allow relighting of the scene.
