Web1. Keras supports 'nearest' and 'bilinear' interpolation now with tensorflow backend. Check the documentation. But the default size value is indeed (2,2) or int value, so in that case your upsampling will be at least double. This code needs Keras 2.2.3 or above. WebApr 13, 2024 · Therefore, an upsampling function is required. The PyTorch framework has several upsampling algorithms: nearest, linear, bilinear, bicubic, and trilinear. In this paper, the experiments tried bilinear and bicubic upsampling algorithms based on MIT indoor67 to validate the MSiSQRT-COV. The results are shown in Table 4. WebIn mathematics, bilinear interpolation is a method for interpolating functions of two variables (e.g., x and y) using repeated linear interpolation.It is usually applied to functions sampled on a 2D rectilinear grid, though it can be generalized to functions defined on the vertices of (a mesh of) arbitrary convex quadrilaterals..
