Abstract |
Template matching has been widely used in the industry for manufacturing and as a quality assessment tool. It is, however, unreliable and technically inefficient when the vision system involved becomes faulty as it readily acquires images with contained noise that further leave the system, which evaluates part of the quality through the logo inscribed, decide on an unexpected match. This study aims to incorporate noise suppression and image enhancement through the use of image restoration algorithms, commonly known as the Median filter and the Wiener method, which utilizes Fourier transformation due to the nature of its algorithm. It is expected that, utilizing the algorithms stated, an accurate match can be decided by the system. This study would also seek to evaluate the effectiveness of the template matching algorithm, Normalized Cross Correlation method, and relate the match returned by this algorithm to the effects done by the image filtration process. This study had proven that the addition of noise suppression techniques increased the accuracy of the match returned by the Normalized Cross Correlation algorithm.

Abstract |
I-Zoom is a mobile application which aims to provide an efficient zooming technique in a mobile route planner. The zooming technique gives the users the capability to take a closer view of the image. As the image is enlarged, more details are shown. The application is implemented in a vectorized map and it generates a path from a node to another. The proponents have the objectives of convenience, improvement and satisfaction in using a mobile map through the intelligent zooming technique. Flash Lite and Flash Emulator were the tools that they used in making the application. The proponents used Rapid Prototyping Method in developing the application. After developing the application, the proponents allowed the respondents to evaluate and test the application. The proponents provided a phone to be used by them, which is N95. The result of the evaluation was satisfactory since majority of the respondents gave positive feedbacks with the criteria given.

Abstract |
Each person has their own set of files that they consider very important and precious. But people tend to intrude on these files and invade privacy. Oftentimes, people neglect these threats and stay unaware of the need for security, especially on mobile devices because these are vulnerable to unauthorized access. Data hiding is currently becoming a necessity because of these threats; and steganography is one of the means of securing files. It allows one to hide files inside another file. STEALTH: File Security for Mobile Devices is a software that gives the intended users some option on how to secure their files. This software was developed using Microsoft .Net Framework, and C# as a tool for coding. It will run on mobile devices with Windows- based Operating System. The users need to have .Net Compact Framework, and the cab file of the application on their devices to begin installation. Once installed, it will then be available for use.

Abstract |
File transfer using an internet connection is the most commonly used because of its availability and because not many people know that file transfer can also be done without an internet connection. Dialup connection can also be used in transferring files to a remote computer through terminal emulators. One of the widely known terminal emulator is the HyperTerminal. Terminal emulators like HyperTerminal connects two computers using a telephone line and a modem and also allows file transfer without an internet service provider. The only problem is that terminal emulators are usually text-based. There is no user friendly interface and commands are executed by manual typing of codes. The application was designed and developed similar to HyperTerminal but with added features such as having an improved Graphical User Interface, User Friendly setup and the ability to view the contents of the remote desktop computer. Testing was done in two remote places within Metro Manila; this is to ensure the efficiency of the application in connecting computers even in remote places. Data Integrity is also part of this application. The application has security mechanism to ensure that only the authorized person can use the application; login password was incorporated in the application. It was found out that a remote computer can be browsed and can transfer a file to another computer even without the use of internet service provider; this is possible with the use of Public Switched Telephone Network dial-up networking. Furthermore the study can be enhanced by making it run on a different platform such as Linux, Mac and many others

Abstract |
Route Navigator is an automated mobile path finder service which aims to provide text direction and map direction through the use of SMS or MMS by using existing services offered by the carrier networks like Sun, Globe and Smart. Users of the service will send a request for path in the proponent’s gateway (the gateway is usually a GSM modem for SMS and ideally GPRS modem for MMS.) The main program will process the request and calculates the path using Dijkstra’s algorithm until it generates a reply to the user (either a text direction or a map.) The text direction provides turn-by-turn instructions while the map provides a visual turn-by-turn instruction on how to traverse the path generated by the program. The proponents have the objective of providing a path and an alternate path to users of the services by means of using any mobile phone in the market that supports the service they need (SMS or MMS). AT commands were used for modem communication between the program and the modem, Flash was used for the Map generation and C# was used as a tool for developing the main programming logic of the whole system. After developing the application it undergone testing and evaluation by letting users text into our gateway and try if the system shall generate the correct information in accordance to what service type they have requested.

Abstract |
The Physiognomy-Neural Networks research aims to combine the ancient psycho-personality technique of Physiognomy (face reading) with the artificial intelligence method of Neural Network graphic pattern recognition. Today, Human Resource Department of corporations need psychologists to help them investigate the character traits of a job applicant, and this method is expensive in terms of time and money. The proposed system is deemed significant to the Human Resource Departments in personality character investigation. The system concentrates on two major aspects of the face, which are the forehead and the lips. The researchers trained the system by acquiring different images of persons in a structured photo-session environment and inputting the captured photos to the system. Surveys were conducted by offering the system to human resource personnel in order to have a sense of the software’s functionality and the program’s acceptability. The system has shown that it has recognized the enhanced features of the images with an acceptable degree of success. |

Abstract |
The proponents developed different system modules of the anti-spyware solution based on the user and systems requirements gathered from the Mapua network users and administrators. The anti-spyware application solution required must detect and clean the spyware using detection and cleanup information stored in an updatable pattern file package for the client module. The pattern file package is a stand alone application that will enable to store and compare the spyware information based on the file detection and cleanup data from its database. Features of the pattern file package will also be designed according to automatic information extraction of the spyware information of a given file sample and security provisions for authorized access of the internal data storage. Details of the detection and cleanup are also presented in a graphical interface. For the server module, a web-based application will also be developed for report generation that will include system logs and report console for the systems administrator.
