NVIDIA DRIVE OS Linux SDK API Reference5.1.9.0 Release |
The NvMedia Tensor Metadata API encompasses all NvMedia Tensor metadata processing.
Tensor metadata processing follows the producer/consumer model:
Modules | |
| Dimension Indices - NCHW | |
| Dimension Indices - NCxHWx | |
| Dimension Indices - NHWC | |
| Stride Indices - NCHW | |
For NCHW tensor, assuming p,q,r,s correspond to N,C,H,W dimensions, the offset from the base address of the tensor to access a tensor value at coordinate (p,q,r,s) is calculated using the expression below: | |
| Stride Indices - NCxHWx | |
For NCxHWx tensor, assuming p,q,r,s correspond to N,C,H,W dimensions, the offset from the base address of the tensor to access a tensor value at coordinate (p,q,r,s) is calculated using the expression below: | |
| Stride Indices - NHWC | |
For the NHWC tensor, assuming p,q,r,s correspond to N,H,W,C dimensions, the offset from the base address of the tensor to access a tensor value at coordinate (p,q,r,s) is calculated using the expression below: | |
| Stride and Dimension Indices | |
| The application can use the stride and dimension indices defined below to access the strides and sizes from the corresponding arrays. | |
