A Sensor Network Approach for Violence Detection in Smart Cities Using Deep Learning.

Citizen safety in modern urban environments is an important aspect of life quality. Implementation of a smart city approach to video surveillance depends heavily on the capability of gathering and processing huge amounts of live urban data. Analyzing data from high bandwidth surveillance video streams provided by large size distributed sensor networks is particularly challenging.

Is Contrast Enhanced Ultrasonography a useful tool in a beginner's hand? How much can a Computer Assisted Diagnosis prototype help in characterizing the malignancy of focal liver lesions?

Aim: Contrast enhanced ultrasound (CEUS) improved the characterization of focal liver lesions (FLLs), but is an operatordependent method. The goal of this paper was to test a computer assisted diagnosis (CAD) prototype and to see its benefit in assisting a beginner in the evaluation of FLLs.

Material And Method: Our cohort included 97 good quality CEUS videos[34% hepatocellular carcinomas (HCC), 12.

Computer aided diagnosis method for steatosis rating in ultrasound images using random forests.

Unlabelled: In this paper we discuss the problem of computer aided evaluation of the severity of steatosis disease using ultrasound images. The AIM of the study being to compare the automatic evaluation of liver steatosis using random forests (RF) and support vector machine (SVM) classifiers.

Material And Method: One hundred and twenty consecutive patients with steatosis or normal liver, assessed by ultrasound by the same expert, were enrolled.
