The aim of this work is to explore the usefulness of face semantic segmentation for head pose estimation. We implement a multi-class face segmentation algorithm and we train a model for each considered pose. Given a new test image, the probabilities associated to face parts by the different models are used as the only information for estimating the head orientation. A simple algorithm is proposed...
In this paper the problem of multi-class face segmentation is introduced. Differently from previous works which only consider few classes — typically skin and hair — the label set is extended here to six categories: skin, hair, eyes, nose, mouth and background. A dataset with 70 images taken from MIT-CBCL and FEI face databases is manually annotated and made publicly available1. Three kind of local...
Multi-View Stereo (MVS) algorithms scale poorly on large image sets, and quickly become unfeasible to run on a single machine with limited memory. Typical solutions to lower the complexity include reducing the redundancy of the image set (view selection), and dividing the image set in groups to be processed independently (view clustering). A novel formulation for view selection is proposed here. We...
A simple and specific method for the simultaneous determination of eleutherosides B and E in powdered rhizomes of Eleutherococcus senticosus extract and in solid and liquid dietary supplements was developed and validated. E.senticosus extracts, often mixed with other plants or herbal extracts, are widely used in food supplements because of the tonic and adaptogenic activities referred to the eleutherosides...
Adaptation for scalable video is one of the recent challenges in video distribution over modern networks, which are heterogeneous both in terms of available bandwidth and user end terminal capability. Scalable Video Coding offers the possibility to adapt the content following the “quality layer” abstraction. In this work we present a new method to optimally define quality layers using Integer Linear...
Adaptation for scalable video coding is one of the recent challenges in video distribution over modern networks, which are heterogeneous both in terms of available bandwidth and user end terminal capability. In case of SNR/spatial combined scalability an interesting issue concerns how to remove data from different spatial resolutions for the adaptation to different rates. Scalable Video Coding offers...
