摘要:
In one example, a plurality of image frames captured by a digital camera unit are received. Received image frames may be still images or frames of a video sequence. Received image frames are automatically analyzed for detecting a possibility to process a plurality of image frames.

The effect of camera shake in digital video is corrected using signal processing techniques. The digital video is a sequence of digital images. When the sequence of digital images are being captured, movement of the imaging device causes the images to shift on the image sensor of the imaging device and affects the quality of the eventual video. Movement of the imaging device is detected while the video is being captured, and a motion information representing the motion is recorded. A processor determines a correcting filter based on the motion information and user input. The processor modifies the sequence of images captured according to the correcting filter and obtains a final corrected video. Corrected video is displayed in a viewfinder.

In an example embodiment, method, apparatus and computer program product are provided. The method includes facilitating receipt of a deconvolved image including a plurality of component images. A guide image is selected from the component images and a cross-filtering is performed of component images other than the guide image to generate filtered component images. The cross-filtering is performed of a component image by iteratively performing, selecting a pixel and a set of neighboring pixels around the pixel in the guide image, computing a set of weights corresponding to the set of neighboring pixels based at least on spatial differences between the pixel and the set of neighboring pixels, and cross-filtering a corresponding pixel of the pixel in the component image based on the set of weights to generate a filtered corresponding pixel in the component image. The filtered component images form a filtered deconvolved image with reduced chromatic aberration.

Disclosed are systems, computer-readable mediums, and methods for detecting glare in a frame of image data. A frame of image data is preprocessed. A set of connected components in the preprocessed frame is determined. A set of statistics is calculated for one or more connected components in the set of connected components. A decision for the one or more connected components is made, using the calculated set of statistics, if the connected component is a light spot over text. Whether glare is present in the frame is determined.

Body art, such as tattoos, are integrated or extended onto clothing. Clothing patterns may be integrated or extended onto body art, such as temporary tattoos. In one embodiment, a computer analyzes an image of a body with a tattoo and generates an image suitable for application to clothing. When applied to clothing, the image displays the portion of the tattoo that is covered by the clothing, or may extend the appearance of the tattoo from the skin to the adjacent clothing.
摘要:
A method and an apparatus for deblurring an image from a sequence of images are described. The image comprises pixels. A motion estimation stage estimates motion of the pixels of the image. A point spread function modeling stage models point spread functions for the pixels of the image using the motion estimates. A deconvolution stage determines a deblurred estimate of the image using the modeled point spread functions. A feedback loop allows iteratively improving the motion estimates for the pixels until the modeled point spread functions converge.

One embodiment includes an artificial vision system mounted on a platform. The system includes an image system comprising a video source that is configured to capture a plurality of sequential images. The image system also includes an image processing system configured, via at least one processor, to process the plurality of sequential images to calculate situational awareness (SA) data with respect to each of the plurality of sequential images and to convert the processed plurality of sequential images to visible images. The system further includes a video display system configured to display the visible images associated with the processed plurality of sequential images and to visibly identify the SA data relative to the platform.

To reduce the difference among a plurality of images acquired due to an object shake or hand shake. An image capturing apparatus 10 includes an imaging optical system 11 and an image sensor 14 that acquires an image of light coming from the imaging optical system 11. The imaging optical system 11 has an aperture stop 12 including a first aperture and a second aperture. The image sensor 11 has first pixels and second pixels. The central axis of the first aperture and the central axis of the second aperture are aligned with each other. The first aperture has a first optical filter that codes light passing therethrough with a first code. The first pixels receive first coded light coded with the first code. The second pixels do not receive the first coded light and receive light other than the first coded light.

Super-resolution of dynamic scenes using sampling rate diversity, processes and systems thereof are provided. The method implementing the processes includes: in a first stage, super-resolving secondary low-resolution (LR) images using a set of primary LR images to create LR dictionaries to represent polyphase components (PPCs) of high resolution (HR) patches of images; and, in a second stage, reverting to a single frame super-resolution (SR) applied to each frame which comprises an entire image, using the HR dictionaries extracted from the super-resolved sequence obtain in the first stage.
