Returns a kernel which has each of its weights multiplicatively inverted. Weights with a value of zero are not inverted and remain zero.
Usage | Returns | Kernel.inverse() | Kernel |
Argument | Type | Details | this: kernel | Kernel | The kernel to have its entries inverted. |
Examples
Code Editor (JavaScript)
var sobelKernel = ee.Kernel.sobel();
print(sobelKernel);
/**
* Output weights matrix
*
* [-1, 0, 1]
* [-2, 0, 2]
* [-1, 0, 1]
*/
print('Inverse of Sobel kernel weights', sobelKernel.inverse());
/**
* [-1.0, 0.0, 1.0]
* [-0.5, 0.0, 0.5]
* [-1.0, 0.0, 1.0]
*/
