Patent number: 9087369Abstract: The invention relates to an apparatus for being used for detecting a property of an object. An ultrasound signal providing unit (2) provides an ultrasound signal, which is indicative of a property of the object (9) at one or several depths within the object (9) and which depends on time, and a periodicity value determination unit (5) determines a periodicity value being indicative of a degree of temporal periodicity of the ultrasound signal for a constant depth. The temporal periodicity of the ultrasound signal at the respective constant depth, i.e. the periodicity value, depends on the property of the object at this depth and can therefore be used for detecting a property of the object.Type: GrantFiled: November 10, 2011Date of Patent: July 21, 2015Assignee: Koninklijke Philips N.V.Inventors: Fei Zuo, Erik Godefridus Antonius Harks, Steven Antonie Willem Fokkenrood, Yingrong Xie, Szabolcs Deladi

Patent number: 8718360Abstract: A color image enhancement method, for enhancing the color of a color image comprising a plurality of pixels. The method comprises: mapping a color saturation value of each pixel to a normalized saturation value, wherein the range of values of normalized saturation is the same independent of the luminance value of the pixel; estimating a probability distribution of the normalized saturation values; defining a transfer function for modifying the normalized saturation values, based on the estimated probability distribution; and applying the transfer function to the normalized saturation values to generate modified values.Type: GrantFiled: October 29, 2010Date of Patent: May 6, 2014Assignee: NXP B.V.Inventors: Yingrong Xie, Michiel Adriaanszoon Klompenhouwer

Publication number: 20110317918Abstract: In a method for color enhancement the color distance between spatially close colored pixel or pixel areas does not change more than a threshold, the threshold being a function of the initial color distance. The color difference between pixels that are close together and did not differ much in color will be restricted. This reduces the change on unnatural looking parts of an image and allows more pronounced color enhancement to be 5 used.Type: ApplicationFiled: December 18, 2009Publication date: December 29, 2011Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Rui Filipe Cardoso Guerreiro, Jeroen Arnoldus Paulus Tegenbosch, Yingrong Xie, Michiel Adriaanszoon Klompenhouwer

The method comprises: mapping a colour saturation value of each pixel to a normalised saturation value, wherein the range of values of normalised saturation is the same independent of the luminance value of the pixel; estimating a probability distribution of the normalised saturation values; defining a transfer function for modifying the normalised saturation values, based on the estimated probability distribution; and applying the transfer function to the normalised saturation values to generate modified values.Type: ApplicationFiled: October 29, 2010Publication date: May 12, 2011Applicant: NXP B.V.Inventors: Yingrong XIE, Michiel Adriaanszoon KLOMPENHOUWER
