Image Processing and Pattern Recognition Chapter 3 : Intensity Transformation and Spatial Filtering
okay , now we talk about the intensity transformation and spatial filtering . actually , what the heck is this ?
well , let’s find out.
Generally now , we are talking about image enhancement that is the second step of the fundamental image processing steps that I mentioned in previous post .
what is enhancement? it is actually a process of increasing the quality of the image or we make the image looks nicer . anyway we’re gonna talk about this further , so just stay relax and enjoy the post..hehehe.
Introduction to spatial
basically , spatial is refers to the image plane. it about direct manipulation of the pixel in the image.
there are 2 categories in this processing :
1. intensity transformation : it’s about manipulation and tresholding the image.
2. spatial filtering : image sharpening and blurring
The simplest image processing technique is gray level transformation
