It is used for smoothing, sharpening, removing noise, and edge detection. We have explored various terms in image filtering in this term paper, going through the spatial domain and frequency domain. In spatial domain simply using masks and linear convolution the image is filtered for blurring, sharpening and noise reduction. In frequency domain the image goes through the circular convolution before which other processing is done. In digital image processing, FFT is applied to convert an image from the image (spatial) domain to the frequency domain. Doing so is important as applying filters to images in the frequency domain is computationally faster than doing the same in the image domain. Further Gaussian filter is also studied in this term paper.

It is a great challenge to design an effective UI as it requires an understanding of different disciplines, for example, the user's physical and cognitive capabilities, sociological contexts, computer science and engineering, graphics design, and work domain. KU Canteen Management System is a food coupon system enabling users to choose food items and pay using card instead of physical money. The system is developed as a desktop application where user logins to the system using an RFID tag. Interface issues like deduction modes, availability of food, font sizes, etc. were addressed through development strategies like persona creation, ethnographic observation, participatory design and evaluated numerous times through expert reviews like heuristic evaluation, cognitive walkthrough, Norman's principle.

Website is the internet advertising and communication billboard for an organization which provides the better visibility about every information needed to be flowed. KUYRCC being a very proficient club in Kathmandu university, it has just recently launched an official site with static message flows, timelines display and other features representing the club. Still with the official launching of the website, recent trend for message flow for this club has been paper based and through Facebook groups which makes the members and visitors unaware of the information. With an objective of developing a viable, usable and dynamic website, “KUYRCC” project, a website development project was initiated. Conducting proper requirement analysis of the website development project, we have developed this website which includes online registration form for new members and online dynamic volunteer forms along the events, which solves the paper-based issues spotted due to existing system. With transparent event updates and notifications, the users can get information about events of the club. Integrating a dynamic event system, provision of updating and deleting the event with authentication and correct verification enabled, this project was developed use JavaScript as programming language, Node JS framework along with Mongo DB as a database, outcoming a viable project.

The major components used are relay, arduino uno and keypad. For display simply serial monitor is used.
