Vehicle plate number is a unique combination of characters and numbers. Hence, it has been used in various application as personal identification such as for parking system identification, security monitoring system and etc. This paper illustrated the double edge detection technique in order to enhance the vehicle plate image, before character recognition process. Firstly, the vehicle image is captured, and then it will be re-sized and cropped until the resolution of image is 300x300. After the re-sized process, First Edge detection is applied to the image. Threshold of black and white are 59 and 60 respectively used to change the image into black and white colour only. Next, Second Edge detection is used to remove the unwanted image and only remain the plate number in white colour. MATLAB software is used in this experiment.
Utility monitoring system plays a vital role for consumers in domestic areas to identify their electric power usage, thus creates awareness, motivates and educates consumers about saving power consumption. This paper develops a monitoring system for electric power usage, designed consisting of a digital meter, display unit, microcontroller, auto-generated data-based logging and communication device. The system is in real-time structure which measures the power usage by hourly basis and displays the results in kWh every time in convenient and organized manner. The data-based logging feature enables utility usage information to be recorded in timely basis. An additional feature provided in this system is a notification module that send charges information corresponding to consumer’s utility usage. Consumers are able to be aware of the utility usage with the corresponding charges at real-time basis as well as capable to predict, control and manage their utility usage on daily manner. Eventually this system is beneficial for both parties which are the consumers and the utility provider.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
