Patent number: 9292947Abstract: To generate a high-quality mosaic image even in a case where a material image having a shape different from that of a region in which the material image is to be placed is used. A target image is divided into a plurality of different-sized regions. The size of a material image is changed in accordance with the area of corresponding one of the regions, and is placed in the region on the basis of the chromatic component of the region. In the case of overlapping material images that have been placed, control processing is performed so that a smaller one of them is placed on a larger one of them.Type: GrantFiled: June 29, 2012Date of Patent: March 22, 2016Assignee: Canon Kabushiki KaishaInventors: Kazuhiro Watanabe, Wataru Kaku, Hiroyuki Fukushima, Kaori Miyake

Patent number: 9288386Abstract: An object of the exemplary embodiment is to make it possible to easily take a group photo of a plurality of persons including a photographer. In a digital camera 1, an image a of other photographed persons is taken by a photographer immediately after an instruction of a composite shooting mode is given. Next, the digital camera 1 is handed over to one of the other photographed persons, by whom an image b of the photographer is taken. When predetermined synthesizing conditions are satisfied, a facial image contained in one of the two taken images a and b shot in series is synthesized with the other taken image so that a new composite image c is created. Thus, a group photo in which all the persons have been photographed can be synthesized easily.Type: GrantFiled: November 16, 2011Date of Patent: March 15, 2016Assignee: CASIO COMPUTER CO., LTD.Inventors: Hitoshi Amagai, Naotaka Uehara, Takayuki Kogane, Sumito Shinohara, Masato Nunokawa, Tetsuya Handa, Kimiyasu Mizuno, Takehiro Aibara

Patent number: 9235780Abstract: To improve feature selection accuracy during a visual search, interest points within a query image are two-way matched to features in an affine transformed image or otherwise transformed version of the query image. A user device implements a method for selecting local descriptors in the visual search. The method includes: detecting a first set of interest points for the original image; computing an affine transform matrix; computing a new image as a transformation of the original image using the affine transform matrix; detecting a second set of interest points from the and new image; performing a two-way matching between the first set of interest points and the second set of interest points; sorting matching pairs according to a specified self-matching score (SMS); assigning an infinite value to SMS of unmatched interest points from the original image; selecting the interest points based on SMS. Significant performance gains reduce false positive matches.Type: GrantFiled: December 9, 2013Date of Patent: January 12, 2016Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Zhu Li, Xin Xin, Abhishek Nagar, Gaurav Srivastava, Kong Posh Bhat, Felix Carlos Fernandes

Patent number: 9042659Abstract: Identification of objects in images. All images are scanned for key-points and a descriptor is computed for each region. A large number of descriptor examples are clustered into a Vocabulary of Visual Words. An inverted file structure is extended to support clustering of matches in the pose space. It has a hit list for every visual word, which stores all occurrences of the word in all reference images. Every hit stores an identifier of the reference image where the key-point was detected and its scale and orientation. Recognition starts by assigning key-points from the query image to the closest visual words. Then, every pairing of the key-point and one of the hits from the list casts a vote into a pose accumulator corresponding to the reference image where the hit was found. Every pair key-point/hit predicts specific orientation and scale of the model represented by the reference image.Type: GrantFiled: June 21, 2011Date of Patent: May 26, 2015Assignee: Telefonica, S.A.Inventors: Tomasz Adamek, Javier Rodriguez Benito
