This paper introduces a system to diagnose the sensitivity toward sound by improving a mechanism based on facial emotions recognition system that combines with IoT protocols and cloud computing. The proposed system has been performed by incorporation of a cognitive IoT environment consisted of hardware and software components with a cloud. This system has been implemented in a laboratory to recognise the behaviour of people suffering from sensitivity to sound. This behaviour has been adopted by monitoring human face emotions through a live video capturing using camera and image processing using facial emotion recognition software. Emotions values obtained was examined and collected in a cloud using the MQTT protocol. These emotions have been categorised as normal and abnormal. Finally, several cases have been tested using this system, and five levels for sound sensitivity has been adopted. Sound intensity values ranged from 10−12 W/m2 up to 10−4W/m2.","PeriodicalId":202291,"journal":{"name":"2019 First International Conference of Computer and Applied Sciences (CAS)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132670818","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}

Local descriptors are common and externally effective for various 3D tasks such as registration, object tracking object recognition and saliency detection. In this paper, we present a suitable solution of saliency regions-based surface patch detection in 3D point cloud images using pairwise 2D histograms of local descriptors constructed from both global and local geometry information. The local information is estimated based on the local descriptor formulated from the relation between 3D point and its neighboring points (neighbourhood points-based descriptor). The global information is estimated by extrusion shape descriptor based radial map construction. The proposed method has three well-defined steps for preprocessing workflow in order to prepare data points for salient region detection process composed of downsampling-outliers removal, normal vector computation for each point and neighbourhood determination for each point. From the experiments, the local shape descriptors adopted in this paper are reliable to detect more salient points-based surface patch detection in the 3D point cloud model. The experiments on a publicly point cloud database were attained high accuracy of the proposed surface patch detector.","PeriodicalId":202291,"journal":{"name":"2019 First International Conference of Computer and Applied Sciences (CAS)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114615785","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}

Such properties can be used to analyse diffusion and confusion processes, which is one of cryptography's key features; a speech scrambling is an important tool in wireless communication systems for enhancing data security. The main target is achieving security to resist malicious eavesdroppers and attacks. This paper presents a speech scrambling model using three various chaotic maps/flows (standard map SM, Unified system US and Chen system CS). The use of the chaotic keys in scrambling techniques are to enhance the transmitted data security, which is strong over the effects of AWGN. Five different tests were included in the evaluation measures: cepstral distance dCD, Linear predict coding distance dLPC, Mean Square Error MSE, Entropy H, and Correlation Factor Rc. The important criteria are residual intelligibility of speech signal between the (original and scrambling/descrambling signal) for the proposed models. The results are good enough to protect the encryption signal of the brute force attack, and when applying a model, the results are being evaluated. The offered model was carried out using SIMULINK (R2018b) by using MATLAB.","PeriodicalId":202291,"journal":{"name":"2019 First International Conference of Computer and Applied Sciences (CAS)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129044458","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}

Therefore it was necessary to have encryption techniques that protect the transmitted information In this study, a new algorithm of colour image encryption based on DNA and the chaotic map is proposed. The diffusion is achieved by using the processes of shifting and permutation, and the confusion is achieved by using the processes of S-box and mathematics. This algorithm was applied to different image sizes and type (bmp, jpeg). The proposed algorithm is intended to be complex and repel attacks. The shifting process is done on colours (R, G, B) from left to right, giving new pixels different from the old ones. The hexadecimal process and box-S are applied to the blue colour to increase confusion. The process of computing of DNA takes place in two colours (red and green). Pixel locations are altered by permutation (R, G, B) become (B, R, G) this process to increase diffusion. Finally, mathematical operation take place (blue, red) decomposes pixels and increase confusion. This algorithm has a highly sensitive key and can cope with various attacks due to the use of DNA computing and chaotic system.","PeriodicalId":202291,"journal":{"name":"2019 First International Conference of Computer and Applied Sciences (CAS)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115174719","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}
