# Types of Image Processing Operations ## Point wise operations - Context free - Can be performed on [[Image Histograms]] - $g(x, y)=M(f(x, y))$ - Example: $g(x, y)=\alpha \cdot f(x, y)+\beta$ ## Neighborhood Operations - Context dependent - $g(x, y)=M(\{f(i, j) \mid(i, j) \in N(x, y)\})$ - Spatial domain ([[Convolution]]) - Frequency domain ([[Discrete Fourier Transform]] - Binary image analysis ([[Mathematical Morphology]]) - [[Connected Component Analysis]] ## Geometric operations - Operation on pixel's coordinates - Independent of pixels value - Context free - Rotation, translation, affine ([[Linear Algebra#Linear Transformations]]) --- ## References
