WebApr 30, 2024 · The kernel slides from left-to-right and top-to-bottom, computing the sum of element-wise multiplications between the input image and kernel along the way — we call this value the kernel output. The kernel output is then stored in an output image with the same (x, y)-coordinate as the input image. WebDescribe its kernel and range and give the dimension of each. If T(ax2+bx+c) = ax2+(b+c)x+(a+b+c) = 0, then clearly a= 0 and c= −b. Thus the kernel of T is the set of all polynomials of the form bx−b= b(x−1). This set has dimension one (x−1 is a basis). The range of T is all polynomials of the form ax2+(b+c)x+(a+b+c).
