Artificial intelligence chatbot is a technology that makes interaction between man and machine using natural language possible. In this paper, we proposed the architectural design of virtual dietition (ViDi), a chatbot that will function as virtual dietitian for diabetic patients. A general a history of a chatbot, a brief description of each chatbots is discussed. We proposed the use of new technique...
Aesthetics is vital in affecting users' usage in Web interaction. In order to measure aesthetics, an application such as aesthetic measurement application (AMA) needs to be created. In the effort of doing so, this article describes the accuracy of our AMA in measuring the aesthetic aspect by comparing the results of our application and users' perceptions in measuring the aesthetics of the Web page...
The Road Transport Department of Malaysia has endorsed a specification for car plates that includes the font and size of characters that must be followed by car owners. However, there are cases where this specification is not followed. This will cause problems in the recognition phase because the existing systems will find difficulty in recognizing characters in car plates. To ensure the recognition...
This paper will study and evaluate watermarking technique by Zain and Fauzi. Recommendations will then be made to enhance the technique especially in the aspect of recovery or reconstruction rate for medical images. A proposal will also be made for a better distribution of watermark to minimize the distortion of the region of interest (ROI). The final proposal will enhance AW-TDR in three aspects;...
This paper discussed security of medical images and reviewed some work done regarding them. A fragile watermarking scheme was then proposed that could detect tamper and subsequently recover the image. Our scheme required a secret key and a public chaotic mixing algorithm to embed and recover a tampered image. The scheme was also resilient to VQ attack. The purposes were to verify the integrity and...
Digital watermarking medical images provides security to the images. The purpose of this study was to see whether digitally watermarked images changed clinical diagnoses when assessed by radiologists. We embedded 256 bits watermark to various medical images in the region of non-interest (RONI) and 480K bits in both region of interest (ROI) and RONI. Our results showed that watermarking medical images...
This paper will discuss the properties of watermarking medical images. We will also discuss the possibility of such images being compressed by JPEG and give an overview of JPEG compression. We will then propose a watermarking scheme that is reversible and robust to JPEG compression. The purpose is to verify the integrity and authenticity of medical images. We used 800times600times8 bits ultrasound...
