As compared to scanners, cameras offer fast, flexible and non-contact document imaging, but with distortions like uneven shading and warped shape. Therefore, camera-captured document images need preprocessing steps like binarization and textline detection for dewarping so that traditional document image processing steps can be applied on them....
US9886628B2 - Systems and methods for mobile image capture ...
Systems and methods are provided for processing and extracting content from an image captured using a mobile device. In one embodiment, an image is captured by a mobile device and corrected to improve the quality of the image. The corrected image is then further processed by adjusting the image, identifying the format and layout of the DL, binarizing the image and extracting the content using ......

image reader is dependent on a human operator. It is difficult for an operator to know the ideal point from where to capture an image of a target such as a document. More often than not, the user captures the image at an oblique angle, i.e. the image reader is not in a plane parallel to the plane of the document, and the captured image is skewed....
An Efficient Junction Detection Approach for Mobile ...
conditional environments [1], [2]. Compared to images captured by professional digital cameras, images acquired from mobile phones are usually of much lower quality. Since table is a very common way to organize information in structured documents, table document image
Binarization of degraded document images based on ...
The persistent difficulties in document image binarization motivated the authors to design a new learning model based on the deep supervised network (DSN) , .According to previous reports, the DSN structure has outperformed regular convolutional neural network (CNN) structures regarding convergence and the test performance , .However the prediction of a single DSN suffers from the loss of low ...
Multi-view Person Re-identification in a Fisheye Camera ...
Person re-identification is a crucial component for multi-camera networks in different real-world applications such as surveillance, automation, and business analytics. Despite considerable recent progress, the performance in practice is still not satisfactory due to the high intra-person variation and significant complexity of the task, including differences in scale, viewing direction, and ...

These processing stages may include functions such as image scaling (digital zoom), (de)warping, windowing, electronic image stabilization, super-resolution, external video overlay, image fusion, and on-screen display. In some cases, the captured and processed video stream may need to be compressed before it is transmitted to a control station....

For example, camera 20 may be a fish eye or panomorphic lens camera 20 and the captured video may require de-warping. The video processing module 82 may be configured to work with the identification module 70 to resize the captured video based on the sub-portion of the video identified using the interest-ratings of the players 110 .

Current OCR systems do not expect these types of artifacts, and have poor performance when applied directly to camera-captured documents. The goal of page de-warping is to flatten a camera captured document such that it becomes readable by current OCR systems. Responsibilities Studied and developed a complete architecture of the project.
US9473758B1 - Methods and systems for game video recording ...
Methods and systems for processing computer game videos for virtual reality replay are disclosed. The method, when executed by a processor, comprises first receiving a video recorded using a virtual camera array during a game play of a source computer game. Next, upscaling the received video to a higher resolution, and interpolating neighboring video frames of the upscaled video for insertion ...
