Transforming Process Models to Problem Frames [chapter]

Stephan Faßbender, Banu Aysolmaz
2016 Lecture Notes in Business Information Processing  
In contrast, Problem Frames modeled using the UML4PF tool can be used for such analysis.  ...  Hence, in this work we propose to integrate UPROM and UML4PF using model transformation. We use eCompany, a project which is part of an e-government program, as running example.  ...  12 The aim of the validation will be to explore if the generated documentation is useful and usable in real-life settings and if the tool supports the application of the method.  ...

Flicker reduction in old films

V. Naranjo, A. Albiol
2000 Proceedings 2000 International Conference on Image Processing (Cat. No.00CH37101)  
This artifact appears as global, quick and random variations of the luminance and contrast between consecutive frames of a sequence.  ...  However, although this method reduces mean and variance variation between frames, it does not yield good visual results. Finally, an algorithm based on the histogram matching is proposed.  ...  This may be because the problem may seem very easy to solve. However, this is not the case, since a simple change in the image mean intensity is not sufficient to solve the problem.  ...

Panoramic view construction

M. Traka, G. Tziritas
2003 Signal processing. Image communication  
Then the parametric models are composed and all the frames are aligned, yielding a whole view of the scene background.  ...  First, point or block correspondence between each pair of successive frames is determined. Three parametric motion models are used: 2-D translation with scale change, affine, and projective.  ...  The process of mosaic construction involves the frames' transformation according to global frame-to-mosaic alignment parameters, which are obtained by composing the frame-to-frame alignment parameters.  ...

A six-parameter affine model is used to describe the interframe transformation, allowing quite accurate description of typical scene changes due to camera motion.  ...  Registration between distant frames is performed efficiently by cascading interframe affine transformation parameters.  ...  An error in estimating transformation parameters between two frames causes incorrect compensating transformations to be applied to a sequence of frames, resulting in annoying jumps in the processed video  ...

Unsupervised Learning of Camera Pose with Compositional Re-estimation [article]

Seyed Shahabeddin Nabavi, Mehrdad Hosseinzadeh, Ramin Fahimi, Yang Wang
2020 arXiv   pre-print
We consider the problem of unsupervised camera pose estimation. Given an input video sequence, our goal is to estimate the camera pose (i.e. the camera motion) between consecutive frames.  ...  Traditionally, this problem is tackled by placing strict constraints on the transformation vector or by incorporating optical flow through a complex pipeline.  ...  This shows that by using the re-estimation process, our model generates images that are more similar to the target frame.  ...
