Digital Image Processing 2nd edition by Gonzalez
Probablity Random Variables and Stochastic Processes 4th edition by Papoulis
Human Odyssey 3rd edition by Kaplan
I spent 6hr online trying to find pdf or ebook files of those books and still cannot find them...they are so expensive so I don't want to buy them ($100+/- USDollar).
Anyone can help me PLEASE?
PS: Half.com and amazon is about $50 for used.
I rather eat $150 of food (for a meal) than buying books.
