Rare event detections are performed using spatial domain and frequency domain-based procedures. Omnipresent surveillance camera footages are increasing exponentially due course the time. Monitoring all the events manually is an insignificant and more time-consuming process. Therefore, an automated rare event detection contrivance is required to make this process manageable. In this work, a Context-Free Grammar (CFG) is developed for detecting rare events from a video stream and Artificial Neural Network (ANN) is used to train CFG. A set of dedicated algorithms are used to perform frame split process, edge detection, background subtraction and convert the processed data into CFG. The developed CFG is converted into nodes and edges to form a graph. The graph is given to the input layer of an ANN to classify normal and rare event classes. Graph derived from CFG using input video stream is used to train ANN Further the performance of developed Artificial Neural Network Based Context-Free Grammar – Rare Event Detection (ACFG-RED) is compared with other existing techniques and performance metrics such as accuracy, precision, sensitivity, recall, average processing time and average processing power are used for performance estimation and analyzed. Better performance metrics values have been observed for the ANN-CFG model compared with other techniques. The developed model will provide a better solution in detecting rare events using video streams.

Problematika lingkungan hidup hingga saat ini kian menunjukkan tingkat yang mengkhawatirkan. Berbagai fakta kerusakan lingkungan yang terjadi di Bumi telah menjadikan penghuninya terusik. Tulisan ini bercorak library research dan berupaya menelisik kontribusi Islam dalam menyelesaikan masalah ini. Hasilnya, Islam member perhatian besar pada berbagai problematika kehidupan manusia, termasuk terhadap lingkungan hidup. Rumusan ini tentu berbeda dengan pandangan ilmuwan modernis Barat yang cenderung menggunakan pendekatan teknis saja, tanpa melihat aspek-aspek lain. Padahal, menggunakan pendekatan teknis semata tidak mencukupi, namun juga membutuhkan pendekatan lain, di antaranya yang bersifat transendental dan profan.Problems of the environment now show an alarming rate. Various facts environmental destruction on Earth has made its inhabitants disturbed. This paper seeks patterned library research and browse for Islamic contribution in solving this problem. As a result, Islam gives a great attention to the various problems of human life, including the environment. This formulation is different from Western modernist views of scientists who tend to use a technical approach only, without looking at other aspects. In fact, using a technical approach alone is not sufficient, but it also requires other approaches, including the transcendent and profane.
