2. Analysis Spatial
• Spatial domain • Image plane • Image processing methods based on
direct manipulation of pixels
3. Background
• Background • • Spatial domain processes denoted by the expression
g(x, y) = T[f(x, y)] – f(x, y) is input image – g(x, y) is output image – T is
an operator on f, defined over some neighborhood of (x, y) – T may
also operate on a set of images (adding two images)
• Spatial domain – Aggregate pixels composing an image –
Computationally more efficient and require less processing resources
for implementation
