دانلود کدهای متلب کتاب پردازش تصویر گنزالس
مطمئنا همه دوستانی که حتی آشنایی مختصری با پردازش تصویر داشته باشن، اسم کتاب Digital Image Processing آقایان Gonzalez و Woods رو شنیدن و ممکنه ازش استفاده هم کرده باشن. همین دو نویسنده یه کتاب با عنوان Digital Image Processing Using Matlab هم به همراه جناب Eddins برای آموزش پردازش تصویر با متلب نوشتن. آقای Eddins هم از توسعه دهندگان متلب و تولباکس پردازش تصویر اون هستن، یه بلاگین هم روی سایت Mathworks.com دارن که مطالب جالب و کاربردی در مورد پردازش تصویر، پردازش سیگنال، تبدیل فوریه و خیلی مباحث دیگه رو اونجا توضیح میدن. کتاب رو هم از لینک زیر می تونین دانلود کنین:
در اینجا کدها و فانکشن هایی که داخل این کتاب تعریف شده رو برای دانلود قرار می دهیم.
