• API description: Applies the nearest neighbor interpolation algorithm to upsample the input signal composed of several input channels.
• Formula:
  • Core algorithm logic:
    1. Scale the destination image to the same size as the source image.
    2. For the points of the scaled destination image, calculate the nearest points of the source image, and copy the values of the latter to the former.
  • Calculation logic:$$d_{src} = min(floor(d_{dst} / scalesD), self\_D - 1),scalesD = outputSize[0] / self\_D$$ $$h_{src} = min(floor(h_{dst} / scalesH), self\_H - 1),scalesH = outputSize[1] / self\_H$$ $$w_{src} = min(floor(w_{dst} / scalesW), self\_W - 1),scalesW = outputSize[2] / self\_W$$ $$out(N, C, d_{dst},h_{dst}, w_{dst}) = self(N, C, d_{src},h_{src}, w_{src})$$

Each operator has calls. First, [object Object] is called to obtain the input parameters and compute the required workspace size based on the process. Then, [object Object] is called to perform computation.
