So, obviously, it is important to include new tools in the socio-sanitary system to maintain and improve the quality of life of the target group. The objective of the proposal described in this paper is to train cognitive abilities (memory, attention, spacial processing…) to promote independent living though a set of serious games (4). These video games serve as a tool to measure partially the cognitive skills of the users and helps to train and improve them. The tests were carried out with 100 people from 3 countries in different socio-cultural contexts. The first levels of each game are played by users several times with good scores, a fact that does not occur in the higher levels that are usually abandoned. However, the subjective feedback received is very promising as they feel they are having fun.","PeriodicalId":111385,"journal":{"name":"2020 IEEE International Symposium on Signal Processing and Information Technology (ISSPIT)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128360840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Applications of UWSNs are numerous such as oil and gas pipeline monitoring, underwater animal detection, and object of interest detection. Automated Underwater Vehicles (AUVs) have been used to monitor underwater environment [13]. One of the significant challenges of AUVs usage is that it does not meet real-time constraints [15]. Researchers in [1] developed a real-time computing system that can collect, process, and transmit data to a gateway in real-time using a single processing node (computer). Nevertheless, a single computer cannot handle the whole load; Resources and equipment in general are limited. Thus, in this paper, we propose two approaches/algorithms that can group master nodes in the network into groups and allocate a computer for each group. In the first algorithm, we cluster master nodes using bottom-up approach. The process of assigning master nodes, in this approach, to groups is based on the communication range. In the second algorithm, nodes are deployed not only homogeneously but also heterogeneously. We add more constraints in order to make our assumptions are closer to real life. In result section, we provide some insights about our experiments. Simulation results show the merit of our proposed approaches.","PeriodicalId":111385,"journal":{"name":"2020 IEEE International Symposium on Signal Processing and Information Technology (ISSPIT)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132950658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many algorithms have been proposed to solve the illumination problem. Most algorithms focus on one image information and only use local illumination change, to improve the effects of removing facial illumination. In this paper, we apply the Expected Patch Log Likelihood (EPLL) algorithm to extract illumination weight and we combine it with the Neighboring Radiance Ratio algorithm (NRR) to optimize the initial vector of the Gaussian mixture model, which makes full use of the redundant information in images. The experimental results on the extended Yale B and CMU PIE face databases show that the proposed algorithm can effectively eliminate the influence of illumination on face images and has a high robustness.","PeriodicalId":111385,"journal":{"name":"2020 IEEE International Symposium on Signal Processing and Information Technology (ISSPIT)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132258636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, with the correct application of different functions and game mechanics, this entertainment can be directed for the good of patients with motor problems, or for elderly people. This research is aimed to study the effectiveness and advantages of computer game platforms in comparison with conventional physical exercise. The experiment involved 13 people. The age of patients ranged from 22-32 (including people with locomotor system problems) to 60-70 years. For each of them the study was divided into two stages: in the first one, the subject was offered to perform a series of physical exercises aimed at warming up the upper and lower body parts. In the second stage, which was held the next day, the subjects performed the same set of exercises, but already in the form of a computer game. After each stage, a pre-prepared survey was conducted which characterized the emotional reaction of each of the subjects to the difference in approaches to rehabilitative physical exercises. The difference in the effectiveness of the game over standard exercises was evaluated by the means of the effectiveness of numerical indicators (table of scores) and the analysis of the therapist. The conducted tests show that at the stage of laboratory testing the average time to pass the current build of the game platform is 512.8 seconds (8.7 minutes), excluding the time to realize the task. The total time including all aspects of the test is 762.6 seconds (12.71 minutes). At the stage of tests with the target audience: the average passing time was 1115.9 seconds (18.5 minutes), the total time was 1809 seconds (30.15 minutes). Evaluating the emotional state and level of motivation shows that player is more interested when hear about an interactive game than the usual physical exercises in front of the mirror. According to the obtained data, it can be concluded that an ordinary set of physical exercises for rehabilitation is more effective if presented as a computer game. The patients have a higher involvement in the process, as well as motivation to improve their results.","PeriodicalId":111385,"journal":{"name":"2020 IEEE International Symposium on Signal Processing and Information Technology (ISSPIT)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116959875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This process of suppression can be performed in many ways but almost always involve recreating some background textures. While recreating it, artists sometimes use common tools and apply smooth transitions to seamlessly blend the result. This operation can decrease the created texture sharpness.

Through computer simulations, it has been verified that SINR degradation caused by user movement can be suppressed by the proposed method compared with the fixed location based design avoiding frequent feedback of information on location with less than 10% increase of energy consumption, except the case all users are moving in a system with small number of cells where improvement is relatively small.

Majority of related work either omits the phase information from the Short Time Fourier Transform (STFT), or uses it for the sole purpose of restoring irregularities in spectrograms. Our process differ, such that it focuses on the phase component of the STFT coefficients to estimate the sound source location by classifying the closest microphone array (node). The image resulting from the mapping of the phase differences information within the time-frequency domain results in what we call phasograms, and are used as inputs to the neural network. Experimentation is achieved through recordings of the first four nodes of the SINS database. For this work, phase difference across adjacent microphones, as well as against the first microphone, were examined. Within a five-fold cross validation, this resulted in an F1-score of 99.68% for the former, and 99.31% for the latter.
