• Perform testing at develop

A memory copy is added on GstBackend from the prediction result after commit 88d0cd0 in order to return a new allocated gpointer not associated with the IPrediction. No performance hits are taken on the tests perform yet since a typical prediction is not of large size, yet the copy could be avoided if the 'IPrediction stayed alive to perform the post-process call.

Properties such as log-level can only take values from 0 to 5, but the plugin is accepting any integer without failing or giving a warning.

GoogLeNet
TinyYolo

Acceptance Criteria:

• Implemented at TinyYolo example.
• Python example to print and compare with Taylor box algorithm

Problem is: that properties are not exposed, needs to make logic for adding parameters.

@mtaylor

Test for Task #9

Tensorflow works with r2i only for ncsdk, user can select backend (TensorFlow)

Bring ideas about real use case application with gst-inference

Create wiki (@josejich )

Upload binaries to RR store (for @carlos-aguero )

C++ plugin
OpenCV

Print text based on GstInference metadata, classifier only

• TensorFlow
• Print results at console

Same demo done by Greivin at x86, but at Xavier.

Add makefiles.
Code Review to tinyYolo example - merge develop

Acceptance Criteria:

• Preprocess and PostProcess ready and being called.
• add metadata on post process function call.

Acceptance Criteria:

• Code is at develop
• Pluging builds
• Is installed and can be used by Gstreamer
• Buffers pass through plugin
• state changes are working

NC_RW_FIFO_TYPE for the input fifo will always be 1 (NC_FIFO_HOST_WO: input fifo), there is no need to expose it as a property.

for r2i and gstinference, just for errors, also integrate to GitHub

Redact as a Gstreamer interface for an user that wants to use it:
Gstreamer properties
input parameters
output parameters
etc.

Check for a model. One day task if not found start with design fix

Goal is to provide a binary for TensorFlow CPU only

Configure should fail if r2inference is not found
