چکیده
Figure 1: A rectangular frame projected into the 2D image. In this section we describe how to calculate the focal length f of the camera assuming the frame to be rectangular. Since we set all other intrinsic camera parameters to default values, the full camera matrix K is then uniquely defined. The following is a detailed explanation of [HZ04] (Example 8.28 page 228). Fig. 1 illustrates the scenario in the 2D image. Let v1 = (

Efficient data structures for piecewise-smooth video processing
A number of useful image and video processing techniques, ranging from low level operations such as denoising and detail enhancement to higher level methods such as object manipulation and special effects, rely on piecewise-smooth functions computed from the input data. In this thesis, we present two computationally efficient data structures for representing piecewise-smooth visual information ...
متن کاملLight Field Photography for CGI/Live Action Video Integration
To separate out objects in a live action video sequence, an artist must step through the footage, frame by frame, and rotoscope out the occluding object from the background where a 3D computer generated graphic is to be inserted. This slow and expensive process can be remedied with the use of light field photography to capture depth information with every frame of film. These depth maps can be ...
متن کاملA Real-Time Image Enhancement System Using Depth From Edge
In this paper, an efficient depth-aware image enhancement system is presented. The depth information and well-known depth-cue relative perception are used to enhance 2D still images or videos. Image enhancement has been developed for decades in a lot of fields. However, conventional approaches deal with images in the 2D(x-y) projective plane. The information of z-axis is not used. In this work,...
متن کاملساختار دهی آنی داده‌‌های مکانی ورودی GIS با تأکید بر عارضه راه
An important issue in implementation of a GIS system is preparation of data to be entered in GIS. To produce spatial data for GIS using photogrammetric techniques, conventional method is to apply photogrammetric and GIS systems individually (off-line procedure). This approach is costly, time consuming and somehow unreliable due to the fact that 3D photogrammetric model is not available at the ...
متن کاملi23 - Rapid Interactive 3D Reconstruction from a Single Image
We present i23, an algorithm to reconstruct a 3D model from a single image taken with a normal photo camera. It is based off an automatic machine learning approach that casts 3D reconstruction as a probabilistic inference problem using a Markov Random Field trained on ground truth data. Since it is difficult to learn the statistical relations for all possible images, the quality of the automati...
