Beyond specific techniques to render real photographs, major challenge is how to understand real photographs as human visual perception and cognition according to artists' painting motivation, which parts should be drawn and how to draw strokes. Before starting to draw with pigments, real artists commonly draw a sketch using simple lines to mark out final stroke layouts which navigate to control stroke drawing trajectories and poses. This can be treated as a blue print in their mind. In SBPR, it is also a powerful tool to guide strokes configuration. In this paper, we propose a image-based method to extract this blue print called guidelines (GL). We generate GL by combining color gradient and morphological structure of real photographs. In the experiment, we apply our GL into Bangladeshi traditional mask automatic animation generation with webcam video. The results show that our method is sufficient and efficient to assist SBPR generation.","PeriodicalId":113626,"journal":{"name":"16th Int'l Conf.

The algorithm makes use of the advantages of both embedding a watermark bit to an individual sample and embedding a bit to a group or frame of samples. Here, a frame of three positive valued samples is used to define the amount of distortion to be added but only the middle sample is distorted based on the decision. Based on the watermark bit either “0” or “1”, the middle sample of a frame is made equal to one of the neighboring samples. Thus, the watermarked audio has a very good perceptual quality. Experimental results show that our new audio watermarking algorithm is not only imperceptible, but also robust against various common signal processing attacks such as amplitude modification, re-sampling, low-pass filtering, re-quantization, MP3 compression, etc. Though proposed in time domain but the algorithm can be implemented in any transform domains with little or no modification.","PeriodicalId":113626,"journal":{"name":"16th Int'l Conf.

Unfortunately, laser data are not free from outliers. Principal Component Analysis (PCA) is a popular method for plane fitting, but it is known that PCA is very sensitive to outliers and gives misleading non-robust results. We present a robust plane fitting algorithm based on PCA coupled with an outlier detecting diagnostic statistical approach. In this method, the recently introduced robust scatter matrix is used to calculate robust statistical distance for finding outliers. After excluding outliers, PCA is performed on the outlier free data which is used for fitting planar surfaces and to estimate robust normal and other parameters. Demonstration of the new algorithm through several synthetic and vehicle based laser scanning data show that the proposed method is efficient, and gives robust estimates. Results outperform Least Squares (LS), PCA and are significantly better than the well-known RANSAC in terms of time, accuracy and robustness. This method has great potential for robust segmentation, surface reconstruction, and other point cloud processing tasks.","PeriodicalId":113626,"journal":{"name":"16th Int'l Conf.

Current Hidden Markov Model (HMM) based ASR systems have solved this problem by using context-sensitive triphone models. However, these models need a large number of speech parameters and a large volume of speech corpus. In this paper, we propose a technique to model a dynamic process of co-articulation and embed it to ASR systems. Recurrent Neural Network (RNN) is expected to realize this dynamic process. But main problem is the slowness of RNN for training the network of large size. We introduce Distinctive Phonetic Feature (DPF) based feature extraction using a two-stage system consists of a Multi-Layer Neural Network (MLN) in the first stage and another MLN with longer context window in the second stage where the first MLN is expected to reduce the dynamics of acoustic feature pattern and the second MLN to suppress the fluctuation caused by DPF context. The experiments are carried out using Japanese triphthong and Japanese Newspaper Article Sentences (JNAS) data. The proposed DPF based feature extractor provides better segmentation performance with a reduced mixture-set of HMMs. Better context effect is achieved with less computation using MLN instead of RNN.","PeriodicalId":113626,"journal":{"name":"16th Int'l Conf.

In this paper, we propose an approach that provides a user to find out news articles which are related to a specific classification. We use our own developed web crawler to extract useful text from HTML pages of news article contents to construct a Full-Text-RSS. Each news article contents is tokenized with a modified light-weight Bangla Stemmer.
