Description

Unable to determine how to use a blob with OpenVINO™ toolkit.

Blob: A blob is a collection of data, often referred to as a tensor or multi-dimensional array in other machine learning frameworks.
SetBlob(): Use the SetBlob() function to specify input/output data for inference. This function can also be used to add additional input data and perform resizing for inputs configured as resizable.
Blob Output Size: The size of the blob output is dependent on the size of the .bin file; larger .bin files result in larger blob outputs.

Refer to Blob Documentation for more information on blob.

Refer to OpenVINO™ Integrations for a high-level description of the process of integrating OpenVINO™ into your application.
