An enhancement of Depth Estimation Reference Software with use of soft-segmentation

چکیده

The current version of MPEG FTV 3DTV reference package (DERS), kindly provided by Nagoya University [1], incorporates block-matching and segmentation tools for better estimation of depth maps. In this document, we present an alternative approach: left and right images are matched with use of soft-segments, and thus block-matching and segmentation are merged in to a single tool. The proposed enhancement has been implemented and integrated with DERS software. The preliminary results (preformed on most of the test sequences) show considerable improvement with respect to quality of synthesized image.

Enhancement of Learning Based Image Matting Method with Different Background/Foreground Weights

The problem of accurate foreground estimation in images is called Image Matting. In image matting methods, a map is used as learning data, which is produced by those pixels that are definitely foreground, definitely background ,and unknown. This three-level pixel map is often referred to as a trimap, which is produced manually in alpha matte datasets. The true class of unknown pixels will be es...

IMAGE SEGMENTATION USING GAUSSIAN MIXTURE MODEL

  Stochastic models such as mixture models, graphical models, Markov random fields and hidden Markov models have key role in probabilistic data analysis. In this paper, we have learned Gaussian mixture model to the pixels of an image. The parameters of the model have estimated by EM-algorithm.   In addition pixel labeling corresponded to each pixel of true image is made by Bayes rule. In fact, ...

Comparing 511 keV Attenuation Maps Obtained from Different Energy Mapping Methods for CT Based Attenuation Correction of PET Data

Introduction:  The  advent  of  dual-modality  PET/CT  scanners  has  revolutionized  clinical  oncology  by  improving lesion localization and facilitating treatment planning for radiotherapy. In addition, the use of  CT images for CT-based attenuation correction (CTAC) decreases the overall scanning time and creates  a noise-free  attenuation  map  (6map).  CTAC  methods  include  scaling,  s...
