In general avoid this book.I purchased this book for a course, and unfortunately this is my first book. Its 95% maths, of course AI is a lot of math, but the book is so abstract and nothing related to practical stuff. Take convolution filters, it gives integrals and all that stuff, but what exactly does it do, how does it perform it on images, and where the heck are sample images, and sample matricies.I bet this author must have sent this book out to teachers so that 50 students would have to buy this over priced book with no practicle use and so hard to read/understand and extremely dense.
