Fast multi-scale joint bilateral texture upsampling
, 2009
"... Abstract We present a new approach using a multi-scale joint bilateral filter for upsampling the synthesized texture generated by optimization-based methods. Our method is based on the following motivation: if the available exem-plar texture is used as a priority to upsample the synthesized texture, ..."

, a high resolution result that prevents image blurring can be obtained. Our multi-scale joint bilateral upsampling applies a spatial filter on each multi-scale layer of the syn-thesized texture, and jointly applies a similar range filter on exemplar texture, which guides the interpolation from low
Fast structure-preserving image retargeting
- in: IEEE International Conference on Acoustics, Speech and Signal Processing, 2009
"... Several different methods have been proposed for image/video retargeting while retaining the content. However, they some-times produce some artifacts, such as ridge or structure twist. In this paper, we present a structure-preserving image resiz-ing technique for the image retargeting applications. ..."

to preserve the content, we introduce the structure constraints derived from the line detection into the large linear system. Then, the mapping matrices are enlarged to the original size by joint-bilateral upsampling and the resized image can be produced to preserve the content and structure as best as pos
Noname manuscript No. (will be inserted by the editor) Dynamic Depth of Field on Live Video Streams: A Stereo Solution
"... effects in live video streams was until recently a quality unique to movie cameras. In this paper, we present a computational camera solution coupled with real-time GPU processing to produce runtime dynamic Depth of Field effects. We first construct a hybrid-resolution stereo camera with a high-res/ ..."

-res/low-res camera pair. We recover a low-res disparity map of the scene using GPU-based Belief Propagation and subsequently upsample it via fast Cross/Joint Bilateral Upsampling. With the recovered high-resolution disparity map, we warp the high-resolution video stream to nearby viewpoints to synthesize a light

1Multi-Frame Demosaicing and Super-Resolution of Color Images
"... In the last two decades, two related categories of problems have been studied independently in the image restoration literature: super-resolution and demosaicing. A closer look at these problems reveals the relation between them, and as conventional color digital cameras suffer from both low-spatial ..."

between the projected estimate of the high-resolution image and each low-resolution image, removing outliers in the data and errors due to possibly inaccurate motion estimation. Bilateral regularization is used for spatially regularizing the luminance component, resulting in sharp edges and forcing
SAMPLING-BASED ROBUST MULTI-LATERAL FILTER FOR DEPTH ENHANCEMENT
"... Depth maps are an integral component of 3D video process-ing. They have a number of uses, including view synthesis for multi-view video, human computer interaction, augmented reality, and 3D scene reconstruction. However, depth maps are often captured at low quality or low resolution due to sen-sor ..."

Our method is based on sample selection and refinement in conjunction with multi-lateral filtering, a method derived from joint bilat-eral

At this pivotal moment it is appropriate to explore the potential for obtaining comprehensive bioinformatics training with currently existing free video resources. This article pre-sents such a bioinformatics curric-ulum in the form of a virtual
Looking beyond the score: The musical role of percussionists’ ancillary gestures

"... [1] The written score frequently serves as the basis for our efforts to understand music's structure, content and meaning. Although scores capture many important aspects of a composition, certain elements are difficult to analyze and impossible to understand without accounting for the way in w ..."
