Ubiquitous access to video is a big engineering achievement in the past decade. It is the accumulated success of research(e.g., video coding, media streaming, network communication), development (e.g., H264, 802.11, Cable Modem/ADSL) and commercialization (e.g., skype, Youtube). So is there still room left for video coding research? I am sure different people have very diverse [...]

Some Thoughts on Image Quality Assessment
Posted in ideas on August 7, 2009 | Leave a Comment »
If you do the citation search on TIP, you will find one of highly cited papers in the area of image processing is Zhou Wang et al.’s work on SSIM image quality assessment (Ref. [1]). It is a very well written paper and contains very thought-provoking experiments on how traditional MSE/PSNR fails miserably in some [...]
Tips for my students (I)

1. Be more selective on reading papers and books. The game of scientific research is a constrained optimization problem – maximize your productivity (in terms of both quality and quantity) subject to certain time constraint. This time constraint simply dictates that you need to more carefully think about how you want to spend your time. [...]

What is common between mind and universe? You might be surprised by the astonishingly similarity between their topology (network or neurons vs. network of galaxies) though they belong to two highly contrasting scales. If there is a grand law governing the evolution of everything including life, intelligence and cosmos, such law must be the simplest [...]

What kind of research has a high impact?
0. Discovery-type: Small-world/scale-free networks, Kleiberg’s Authoritative sources, self-similarity of internet traffic, emergent property of social, economic and biological systems.
If Old One creates this world by a simple rule, discovery of this rule is the holy grail of all scientists. The rule is there – just go and [...]
What I have learned from “poor-quality” PDF files?
Posted in tips on December 9, 2008 | 1 Comment »
For a long time (at least a year), I was bothered by a problem with some pdf files – they appear really lousy on my computer screen. Unless I zoom to >150% under Acroread, texts in those PDF files are just terrible – primarily due to aliasing. So I even had developed a habit of [...]
