# Tensorflow C++ Image Recognition Demo
|
|
|
|
This example shows how you can load a pre-trained TensorFlow network and use it
|
|
to recognize objects in images.
|
|
|
|
## Description
|
|
|
|
This demo uses a Google Inception model to classify image files that are passed
|
|
in on the command line. See
|
|
[`googlenet_labels.txt`](data/googlenet_labels.txt)
|
|
for the possible classifications, which are the 1,000 categories used in the
|
|
Imagenet competition.
|
|
|
|
## To build/install/run
|
|
|
|
As long as you've managed to build the main TensorFlow framework, you should
|
|
have everything you need to run this example installed already.
|
|
|
|
To build it, run this command:
|
|
|
|
```bash
|
|
$ bazel build tensorflow/examples/label_image/...
|
|
```
|
|
|
|
That should build a binary executable that you can then run like this:
|
|
|
|
```bash
|
|
$ bazel-bin/tensorflow/examples/label_image/label_image
|
|
```
|
|
|
|
This uses the default example image that ships with the framework, and should
|
|
output something similar to this:
|
|
|
|
```
|
|
I tensorflow/examples/label_image/main.cc:200] military uniform (866): 0.902268
|
|
I tensorflow/examples/label_image/main.cc:200] bow tie (817): 0.05407
|
|
I tensorflow/examples/label_image/main.cc:200] suit (794): 0.0113195
|
|
I tensorflow/examples/label_image/main.cc:200] bulletproof vest (833): 0.0100269
|
|
I tensorflow/examples/label_image/main.cc:200] bearskin (849): 0.00649746
|
|
```
|
|
In this case, we're using the default image of Admiral Grace Hopper, and you can
|
|
see the network correctly spots she's wearing a military uniform, with a high
|
|
score of 0.9.
|
|
|
|
Next, try it out on your own images by supplying the --image= argument, e.g.
|
|
|
|
```bash
|
|
$ bazel-bin/tensorflow/examples/label_image/label_image --image=my_image.png
|
|
```
