Stride and Dimension Indices

Detailed Description

The application can use the stride and dimension indices defined below to access the strides and sizes from the corresponding arrays.

For example, the stride indices are used to access dimstrides[] in the NvMediaTensorMetaData structure.

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:
