My Assignment in Simple Image Compression Utility Website Evaluation and Other Journal Paper Presentation

My Impression About This Course

Overall I really enjoyed the class, the materials were not complicated and interesting, the links shows to interesting page, the quiz helped me focus on the important part, the assignments were exciting where we get experiment in compressing image, analyzing website, making video presentations, and watched other's videos that had interesting topics. I liked this course because it's very flexible that I can attempt them on my leisure time on Saturday and Sunday for example with almost no burden. The course also reminds me what I did for my bachelor thesis, which is applying discrete wavelet transform on an image in application of wireless sensor network.

The last section of the lecture was very difficult about user interface and universal design which the standards that was pointed to personally bear too much information. It's better to provide examples of a good and not okay page. For the videos I preferred accessing the through Youtube alike, maybe it can be note on the assignment to submit the file and recommended to upload them to Youtube. For the bandwidth consumption there's an option of introducing very high compression technique like x264. About the comment I said during the final face to face class, I thought that we should evaluated others presentation like the method on the picture below:
