This paper is an up-to-date short overview of the QoS for Satellite IP networks. Some definitions, parameters and requirements for QoS are given. IP QoS Architectures are presented and various contributions to end-to-end QoS at each layer are included. DVB-RCS and evolution to standard DVB-S2 - RCS to support emerging Internet services via satellite is also briefly approached. Possible integration with Next Generation Network (NGN) architectures in order to meet their QoS requirements is presented. The horizontal integration of the satellite segment into an IMS network may provide a consistent QoS management across the entire network, while mechanisms defined in the IMS framework bring flexible and performant QoS support to the session and network.

Inter-vehicle communication (IVC) is a key component enabling the autonomous driving vehicles. Standardization of IVC is advanced but yet improvements are still introduced. Congestion control is one of the sensitive topics. The IVC European standard ITS-G5 addresses the congestion issue enabled by a geo-networking protocol that exploits at networking level the geographic information. Implementation of the ITS-G5 standard onto low cost, open source, embedded systems for testing purposes is a challenge, and this is addressed in this paper.

In this paper, we made the emotion recognition for Romanian language using EMO-IIT database with seven emotions (joy, sadness, fury, neutral tone, anxiety, disgust and boredom). Compared to our previous studies we introduced two new emotions: disgust and boredom and a new set of sentences in order to express better the emotional states. The best recognition rate of emotions is around 75% and was obtained for feature vectors which includes MFCC (Mel Frequency Cepstral Coefficients) + PARCOR (Partial Correlations Coefficients) + LAR (Log Area Ratios Coefficients). The accuracy rates are closed to the other studies from the literatures. For example, for the German emotional database EMO-DB which contains all seven emotions, the accuracy recognition rate reported by the researchers was around 85%. The disgust is often recognized as boredom (15%) or neutral tone (10%). The sadness is confused with the neutral tone (12%) and disgust (9%). The main difference between the two databases is that the EMO-IIT contains unprofessional voices with recordings provided by students and EMO-DB contains professional voices, recorded from actors.

A bi-dimensional filter for high accuracy image processing is implemented by using a novel partitioning method. The method is based on a number theory theorem, which permits to reduce the complexity of the operation to that of an adder chain and also the amount of the coefficients stored in memory, improving the memory organization. To show the advantage of such method, we implemented a Floating Point 32 (FP32) in hardware filtering applications and, in particular, for 2D FIR filters. Using Xilinx Virtex 7 Field Programmable Gate Array (FPGA) we obtain a critical path delay of 4.7ns which is comparable with the state-of-art.

This work presents the use of digital watermarking for applications of automated pigmented skin lesions assessment. Automated skin lesion assessment by digital image processing of macroscopic pigmented skin lesion (MPLS) images uses lesion characteristics for malignant risk computation. The accuracy of the computed risk level is increased when additional information is taken into consideration: age, gender, skin type, position of the lesions on body, and the presence of multiple and similar lesions. We propose a digital watermarking scheme for embedding relevant patient information into the color MPSL image. The preliminary experimental results are promising, and suggest that the proposed watermarking scheme is suitable for this type of application.

This paper presents a performance comparison between two current sense amplifiers (CSA) architectures, designed, simulated and implemented in a typical low cost BCD technology. The evaluation was done considering the main parameters that affect the sensing accuracy and both proposed low power circuits have been benchmarked against market available products.

This paper revisits the recently proposed adaptive pairwise reversible watermarking scheme of IEEE Trans. on Image Processing 2016 and investigates a different pairing that favors the grouping in the horizontal direction. The horizontal grouping imposes a new prediction scheme, a different complexity measure, a new pixel selection procedure and several other adjustments. For some test images, the newly proposed scheme outperforms the 2016 adaptive pairwise approach.

A procedure for laboratory rats tracking using image and video processing techniques is proposed. A plastic box split into three chambers by two walls is the analyzed scene. Each experiment starts with a sequence during at least eight minutes with a free rat placed in the middle area with the closed doors to the box marginal locations. The proposed method determines for each sequence frame the location of the rat head. For the second part of the experiment, with open doors, the procedure will be completed later on with the computation of free rat overall motion parameters and identification of specific rat behaviors.

The paper reports comparative performances of five distinct algorithms used for rain removal from single images. Both synthetic and real images are considered, while taking into account standard figures of merit such as PSNR, VIF and SSIM. The experiments revealed that the Gaussian Mixture Model based approach yields best performances in terms of visual quality.

We here present a solution to solve a big data problem in the context of satellite image processing. We conceived a simulator for denoising Sentinel 1 SAR Single Look Complex images, by using block processing together with a method based on the Hurst parameter estimation in the wavelet domain. We compare our method with traditional denoising filters.
