Patent number: 9864929Abstract: This disclosure concerns processing of electronic images, such as hyperspectral or multispectral images. A processor performs a method for estimating an illumination spectrum of an image which defines an input spectrum for each point of the image. The processor determines for each point of a first set of points a measure of variation in relation to the input spectrum of that point. The processor then selects one point from the first set based on the measure of variation. The processor determines a cluster of points based on the input spectrum of the selected point and determines an estimate for the illumination spectrum based on the input spectra of points in the cluster. Since the processor selects a point based on the measure of variation and then determines a cluster based on that point, it performs better than using other methods where the cluster is determined based on a random starting point, for example.Type: GrantFiled: May 2, 2014Date of Patent: January 9, 2018Assignee: NATIONAL ICT AUSTRALIA LIMITEDInventors: Lin Gu, Cong Phuoc Huynh, Antonio Robles-Kelly

Patent number: 9754181Abstract: The disclosure concerns processing of electronic images, such as hyperspectral or multispectral images (302) to determine an output color value for a component spectrum of a decomposed multispectral or hyperspectral image. A processor (120) first determines or accesses the component spectrum and a first color value for the component spectrum and receives an input color value for a pixel location in the image, wherein the component spectrum contributes to the pixel. The processor (120) then determines the output color value for the component spectrum based on the first color value for the component spectrum, the input color value and a utility score and stores the output color value for the component spectrum on a datastore (118). It is an advantage that the processor (120) receives a color value for a pixel location but the output color value is not exactly the received color value but one that is determined based on a utility score.Type: GrantFiled: November 2, 2012Date of Patent: September 5, 2017Assignee: NATIONAL ICT AUSTRALIA LIMITEDInventors: Antonio Robles-Kelly, Cong Phuoc Huynh, Lin Gu
