IMAGE AND KERNEL Math 21b, O. Knill
abel.math.harvard.edu › handouts › imagekernelThe image of a linear transformation ~x7!A~xis the span of the column vectors of A. The image of a linear transformation contains 0 and is closed under addition and scalar multiplication. KERNEL. If T: Rn!Rm is a linear transformation, then the set fxjT(x) = 0 gis called the kernel of T. If T(~x) = A~x, then the kernel of Tis also called the ...
Image Kernels - Explained Visually
https://setosa.io/ev/image-kernelsAn image kernel is a small matrix used to apply effects like the ones you might find in Photoshop or Gimp, such as blurring, sharpening, outlining or embossing. They're also used in machine learning for 'feature extraction', a technique for determining the most important portions of an image.

7.2 Kernel and Image of a Linear Transformation
math.emory.edu › ~lchen41 › teaching7.2. Kernel and Image of a Linear Transformation 383 Theorem 7.2.1 LetT :V →W be a linear transformation. 1. ker T is a subspace ofV. 2. im T is a subspace ofW. Proof. The fact that T(0)=0 showsthat ker T and im T contain the zero vector ofV andW respectively. 1. If v and v1 lie in ker T, then T(v)=0=T(v1), so T(v+v1)=T(v)+T(v1)=0+0 =0

The kernel of T, also called the null space of T, is the inverse image of the zero vector, 0, of W, ker(T) = T 1(0) = fv 2VjTv = 0g: It’s sometimes denoted N(T) for null space of T.
