Hi.I am trying to load an image in QVGA format into a ARM Compute Library ICtensor. This is my current code:
CLTensor in0; in0.allocator()->init(TensorInfo(TensorShape(320U, 240U), 1, DataType::U8));
But in Compute Library "Image" are dined with a Format and dimensions expressed as [width, height, batch].And a Tensor is defined by a DataType plus a number of channels (Always expected to be 1 for now) and their dimensions are expressed as [width, height, feature_maps, batch].
So, what is suggested to use for the parameters "batch" and feature_maps?
and thanks for using Arm Compute Library. In order to use the RGB or RGBA format, you should initialize your tensor in the following manner:
CLTensor in0; in0.allocator()->init(TensorInfo(320U, 240U, Format::RGB));
in this manner you create a 2D tensor with 3 channels (RGB) interleaved. However, just few operations are supported with this data layout so I suggest to convert your input QVGA in a planar data layout (each plane stores the values of each channel). In this manner you can use most of the functions available for Compute Library.
You might have something like:
// Convert to data layout to planar using CLChannelExtract and CLChannelCombine
The output of CLChannelCombine should be:
CLTensor out; out.allocator()->init(TensorInfo(TensorShape(320U, 240U, 3U), 1, DataType::U8));
Hope this can help.
Do not hesitate to write on github (github.com/.../issues) if you need any further information.
