Basic function to execute laplacian reconstruction.
This function calls the following NEON kernels and functions:
This function reconstructs the original image from a Laplacian Image Pyramid.
The input image is added to the last level of the Laplacian pyramid L(n-2), the resulting image is upsampled to the resolution of the next pyramid level.
I(n-2) = upsample( input + L(n-1)
For each pyramid level i, except i=0 and i=n-1: I(i-1) = upsample(I(i) + L(i))
output = I(0) + L(0)

Constructor.
void configure | ( | const IPyramid * | pyramid, |
ITensor * | input, | ||
ITensor * | output, | ||
BorderMode | border_mode, | ||
uint8_t | constant_border_value | ||
) |
Initialise the function's source, destinations and border mode.
The Output image must have the same size as the first level of the pyramid. The Input image must have the same size as the last level of the pyramid.
The idea is to reconstuct the original hi-res image from a low-res representation of it and the laplacian pyramid.
[in] | pyramid | Laplacian pyramid tensors, Data type supported at each level: S16. |
[in] | input | Source tensor. Data type supported: S16. |
[out] | output | Output tensor. Data type supported: U8. |
[in] | border_mode | Border mode to use for the convolution. |
[in] | constant_border_value | (Optional) Constant value to use for borders if border_mode is set to CONSTANT. |
