Publication number: 20130243330Abstract: A method and an apparatus for constructing an image blur pyramid, and an image feature extracting circuit are disclosed. The image blur pyramid construction apparatus comprises a first image blur circuit, a second image blur circuit and an image sub-sampler. The first image blur circuit and the second image blur circuit simultaneously generate a first interval and a second interval in the same octave according to an input image, a first filter and a second filter. The dimension of the second filter is greater than that of the first filter. The image sub-sampler couples with the second image blur circuit and down samples the second interval to generate a sub-sample image.Type: ApplicationFiled: August 20, 2012Publication date: September 19, 2013Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Liang-Chi Chiu, Yen-Chung Chang, Jiun-Yan Chen, Jwu-Sheng Hu, Tian-Sheuan Chang
