A robust hand-gesture recognition system based on a novel descriptor called Volumetric Spatiogram of Local Binary Patterns is presented, which allows a more natural input interface for simulating a mouse. The recognition stage based on Support Vector Machines triggers different mouse functions depending on the recognized gesture.

We developed a new compact 8K Super Hi-Vision (SHV) recorder with a removable recording medium. We proposed a new recording method to improve the recorder's compressed image quality and confirmed its validity by simulation. Integrating the recorder with the method enables high quality recording of SHV at 60 fps.

Game-based learning (GBL) is promising, almost as promising as learning when sleeping. But why does it work? And how to implement it? For which purpose is it appropriate? And when is GBL doomed to fail? Serious games design is an art. How can game designers and developers utilize deep and well-established results of the humanities to make the design and implementation of digital games for learning a routine process? The understanding of digital role-playing based on theories of social psychology such as symbolic interactionism leads to the authors' original generic approach to game-based learning design. A serious game has already been designed, implemented, and evaluated for language learning that runs on conventional computers, as well as on varying mobile devices such as tablets. The stage is set for a series of similar role-playing games which allow for learning in largely varying domains.

This work utilizes the coding information in HEVC for video copy detection. Both directional modes and residual coefficients of the I-frames are employed as the texture features for matching. These features are robust against different quantization parameters and different frame sizes. The accuracy is comparable with traditional pixel domain approaches.

High Dynamic Range photography involves fusing bracket images taken at different exposure values in order to compensate for the low dynamic range of image sensors in digital and smartphone cameras. Bracket images normally consist of an image taken by the auto-exposure setting of a camera as well as two other images at ±n exposure values where n is manually specified or selected. This paper discusses a method to automatically and optimally select exposures by using pixel clustering and local entropy. The results obtained show that the developed automatic exposure selection method provides more scene details compared to the manual or fixed exposure selection.

This paper tries to address the problem of removing unwanted reflection layer from the image mixtures. These reflections may occur due to semi-reflective glass mediums. This demands separating the input image into the reflecting layer and the subject layer, also known as, background layer which is the actual scene itself. But decomposing a single input image into these two layers is a massively ill-posed problem with infinite combinations of decomposition. This type of problem falls under the category of blind source separation. There are ample classical separation approaches available in the literature which either requires multiple images or works on a single image with user assistance. In this paper we propose a method for separating the two layers from a single input image without any user or human intervention using some prior information about the reflective layer.

A fast intra-mode decision algorithm for High Efficiency Video Coding Range Extension (HEVC RExt) is presented. In the HEVC RExt encoder, the encoding performance of intra-coding is better than the previous HEVC still image encoding standard. In order to use textural information of the most probable mode for intra-prediction, the probability distribution of local binary patterns is analyzed. An intra-mode decision method is proposed based on use of the local binary pattern in the texture of an encoded block. Experimental results achieved a 14.59%, on average, time-saving, and a 0.69% and a 0.19 dB loss for bit-rate and PSNR, respectively.

This paper describes a hybrid cryptographic model for secured telecommunication in marine environment. The experimental process consists of four parts. The first step provides a secure way of sharing a key between Vessel Traffic Service (VTS) and Automatic Identification System (AIS). The second step enables them to exchange messages with communication safety, modifying original text to cipher one or reversely. The third step guarantees data integrity, checking whether the messages have been altered by hackers or not. The last step performs frequently replacing the key value in which has been used. The result from the fusion of the cryptography was simulated on Very High Frequency (VHF) devices.

The advent of the state-of-the-art video coding standard, High Efficiency Video Coding (HEVC) is expected to bring great changes to relevant fields of broadcasting, storage and communications. HEVC achieves higher coding gains compared to its previous video coding standards in terms of rate-distortion (R-D) performance with various improved coding tools. This leads to heavy computational complexity and costs to HEVC encoders and these comes as strong restrictions specially to develop H/W types of encoders that are more preferred for real-time based applications and services. In particular, the quad-tree based coding unit (CU) structures with various sizes are known to contribute to achieving high coding gains of HEVC. However, RD cost calculation for mode decision with all CU sizes cannot normally be considered in the H/W HEVC encoders for real-time operation. To overcome this, a CU size pre-determination method based on a probabilistic decision model fit to implement H/W HEVC encoders is proposed in this paper. All available CU sizes are checked before inter prediction and unnecessary CU sizes are excluded from inter prediction according to the decision model. Then inter prediction with the reduced number of CU sizes can be performed in parallel with pipeline structures. The experimental results show that the proposed method effectively determines the necessary CU sizes with negligible coding loss of 1.57% for LD (Low-delay) coding structure and 1.08% for RA (Random access) coding structure, respectively in BD-BR.
高效视频编码(High Efficiency video coding, HEVC)标准的出现，将给广播、存储、通信等相关领域带来巨大的变化。HEVC通过各种改进的编码工具，在率失真(R-D)性能方面实现了比以前的视频编码标准更高的编码增益。这导致HEVC编码器的计算复杂性和成本很高，特别是开发H/W类型的编码器，这些编码器更适合基于实时的应用和服务。特别是，基于四叉树的不同大小的编码单元(CU)结构有助于实现HEVC的高编码增益。然而，在实时运行的H/W HEVC编码器中，通常不能考虑所有CU尺寸的模式决策的RD成本计算。为了解决这一问题，本文提出了一种基于概率决策模型拟合的CU尺寸预确定方法，用于实现H/W HEVC编码器。在进行相互预测之前检查所有可用的CU大小，并根据决策模型将不必要的CU大小排除在相互预测之外。然后，减少CU尺寸数量的相互预测可以与管道结构并行进行。实验结果表明，该方法可以有效地确定所需的CU大小，在BD-BR中，LD (Low-delay)编码结构和RA (Random access)编码结构的编码损失分别为1.57%和1.08%，可以忽略不计。

In this paper we introduce a novel face representation method called Cross Local Binary Patterns(XLBP) to improve the robustness of face recognition for partially occluded and non-uniformly illuminated face images. In our method we use Radon transform to capture the coarse level shape information and XLBP to capture the texture information. Individual histograms computed on each sub-block of the face image and are concatenated in spatial pyramid fashion to get the complete face descriptor. Distance measures based on Pyramid Matching Kernel(PMK) is used to match these face descriptors. Experiments on FERET and YaleB databases show the significance of this method.
