A system and process for identifying corresponding points among multiple images of a scene is presented. This involves a multi-view matching framework based on a new class of invariant features. Features are located at Harris corners in scale-space and oriented using a blurred local gradient. This defines a similarity invariant frame in which to sample a feature descriptor. The descriptor actually formed is a bias/gain normalized patch of intensity values. Matching is achieved using a fast nearest neighbor procedure that uses indexing on low frequency Haar wavelet coefficients. A simple 6 parameter model for patch matching is employed, and the noise statistics are analyzed for correct and incorrect matches. This leads to a simple match verification procedure based on a per feature outlier distance.

Methods and apparatus for processing collections of images are described in which metadata from a set of images may be used in directing a multi-image processing workflow. One or more output images may be rendered from a set of input images, with each output image being some combination of two or more of the input images. To render an output image, a workflow including one or more processing steps may be applied to the images. Metadata may be used in directing and performing the workflow. For example, metadata may be used in determining a particular workflow for a set of images. As another example, metadata may be used to sort a collection of images into multiple categories for automated workflow processing. As yet another example, metadata may be used to retrieve information stored in a profile database that may be used in processing the images.

A system and method for editing images. A simple but powerful image stack is employed in creating an enhanced image from a stack of registered images. This paradigm combines pixels using multi-image operations on the image stack. Image Stacks can help create group photographs, create high dynamic range images, combine images captured under different lighting conditions, remove unwanted objects from images, and combine images captured at different times and with different focal lengths.

A curved-surface display panel fabrication method for fabricating a curved-surface display panel using a flat display panel having a first substrate and a second substrate includes: paring partially outer surfaces of the first substrate and the second substrate so as to reduce thicknesses thereof to a predetermined thickness; bending the pared flat display panel to a desired curved shape; attaching a first guide member which has a shape corresponding to the desired curved shape to the first substrate with a predetermined gap from the pared outer surface thereof and attaching a second guide member with has a shape corresponding to the desired curved shape to the second substrate with a predetermined gap from the pared outer surface thereof; and forming light transmitting reinforcing layers respectively in a space between the first guide member and the first substrate and a space between the second guide member and the second substrate.

An apparatus for imaging a scene is provided. The apparatus including: a charged coupled device (CCD) in optical communication with the scene along an optical path; a multi-image lens disposed in the optical path, the multi-image lens having two or more facets, each facet transmitting an image of the scene to the CCD; and a device which isolates one of the images from each of the two or more facets, such that only the isolated image is incident upon the image capturing means at any instant.

The invention discloses a multi-image splicing method. The method includes the following steps: a memory space corresponding to a whole display screen is divided into more than two sub-blocks; the corresponding relationship between each source-video and the sub-block is defined; wherein, one source-video corresponds to more than one sub-block which can just correspond to one source-video; the sum of each sub-block corresponding to each source-video is regarded as a sub-memory-space corresponding to the source-video; the image of the source-video is scaled into a target image according to the size of the sub-memory-space corresponding to each source-video; the target image data of each source-video is written into the sub-memory-space corresponding to the source-video; an video image is read from the memory space corresponding to the whole display screen and displayed on the display screen. The invention also discloses a multi-image splicing device. The technical proposal of the invention can be flexibly realized and can save memory source.

The embodiment of the invention discloses a method for setting multi-picture, which comprises the following steps that: a video equipment receives a switching command of a user, wherein the switching command comprises sub-picture information to be switched in the current display mode, and the video equipment switches video sources and sub-picture of the multi-picture screen in the video equipment according to the switching command. The method has the advantages of simplified process of sub-picture setting or switching in the multi-picture setting and improvement of easy operation of the equipment, and no influence on the watching of other sub-pictures when adjusting multi-picture.

Embodiments of the invention describe a method for reducing a blur in an image of a scene. First, we acquire a set of images of the scene, wherein each image in the set of images includes an object having a blur associated with a point spread function (PSF) forming a set of point spread functions (PSFs), wherein the set of PSFs is suitable for null-filling operation. Next, we invert jointly the set of images and the set of PSFs to produce an output image having a reduced blur.

A multi-image acquisition apparatus for use in a biometrics system includes a light splitting filter for reflecting or transmitting multi-image lights representing an image of a target subject provided along an identical light path into different bands; a first image sensor for imaging an iris area by capturing a fraction of the multi-image light which has been transmitted through the light splitting filter; and a second image sensor for imaging a facial area by capturing a fraction of the multi-image light which has been reflected from the light splitting filter. The apparatus further includes a control module for controlling the first image sensor and the second image sensor and providing the images obtained by the first sensor and second sensor for image recognition.

The invention relates to the multi-video seamless splicing technology. Calibration of a relative position relation between multiple videos is needed. The invention proposes a multi-video seamless splicing method and a splicing panoramic camera apparatus taking a fish-eye panoramic camera as a reference. The apparatus comprises a fish-eye panoramic camera and a camera array formed by a plurality of common cameras. The fish-eye panoramic camera photographs a panoramic image in a 180 DEG view. The camera array photographs common videos which are used for the multi-video splicing. According to the method, all the cameras in the camera array are in registration with the panoramic image, a relative position relation between the camera array and the panoramic camera is established, and the seamless splicing of the multiple videos are conduced according to the relative position relation. The method and the apparatus have the advantages such as low demand for overlapping field of vision, and good robust performance of registration, and solve a problem of poor image splicing effect caused by low image registration precision in a conventional spliced panoramic camera composed of multiple common cameras.
