annie-capture-demo-python-app

This is a quick python demo application hacked using AMD NN inference engine.

Steps:

1. Convert net.caffemodel into NNIR model using the following command

        python caffe2nnir.py <net.caffeModel> <nnirOutputFolder> --input-dims n,c,h,w [--verbose 0|1]
   

2. Compile NNIR model into OpenVX C code with CMakelists.txt for compiling and building inference library

        python nnir2openvx.py <nnirModelFolder> <nnirModelOutputFolder>
   

3. Copy .so's into annieCapture

Copy the libannmodule.so,libannpython.so, & weights.bin built inside the resnet50-build folder into the annieCapture folder.

4. Run ANNIE Capture

To run the capture make sure that you have a webcam connected and run the following command inside the annieCapture folder.

python annieCapture.py 

Script Inputs:

--image [input image file     - required]
--imagefolder [input Image Directory - required]
--capture [0/1] - (camera input - required)
--pm - [preprocess multiply(as per trained model) - required]
--pa - [preprocess add(as per trained model) - required]
--annpythonlib - [pythonlib - optional]
--weights - [weights.bin - optional]
--labels - [labelfile.txt - optional]
--hierarchy - [hierarchyfile - optional]
--resultsfolder - [output results directory - optional]

Sample (for Resnet)

python AnnieCapture.py --capture [0/1] --pm 1 --pa 0 --annpythonlib <annpythonlib> --weights <weights.bin> --labels labelfile.txt --hierarchy <hierarchyfile>

python AnnieCapture.py --imagefolder <input image directory> --pm 1 --pa 0 --annpythonlib <annpythonlib> --weights <weights.bin> --labels labelfile.txt --hierarchy <hierarchyfile>

python AnnieCapture.py --image <input image file> --pm 1 --pa 0 --annpythonlib <annpythonlib> --weights <weights.bin> --labels labelfile.txt --hierarchy <hierarchyfile>

Key Press Options when in capture mode:

Press these different keys to switch between modes (uses openCV)

1. Keys '1' through 'n' - Runs through a folder corresponding to number once and goes back to live mode (currently supports keys 1,2 folders)

2. Key 'f' - Runs through a folder until asked to change

3. Key 'q' - Quits from the program

4. Key 'Space Bar' - pauses the capture until space bar pressed again

Key Press Options when in imagefolder mode:

Press these different keys to switch between modes (uses openCV)

1. Key 'c' - Switches to camera capture mode until asked to change

2. Key 'q' - Quits from the program

3. Key 'Space Bar' - pauses the capture until space bar pressed again
