android_tflite's Introduction

GPU Accelerated TensorFlow Lite applications on Android NDK.

Run and measure the performance of TensorFlow Lite GPU Delegate on Android NDK.

1. Applications

Age Gender Estimation

Detect faces and estimage their Age and Gender
based on pretrained model of https://github.com/yu4u/age-gender-estimation

3D Handpose

3D Handpose Estimation from single RGB images.

Iris Detection

Eye position estimation by detecting the iris.

Depth Estimation (DenseDepth)

Depth Estimation from single images.
based on pretrained model of https://github.com/ialhashim/DenseDepth

Semantic Segmentation

Assign semantic labels to every pixel in the input image.

Selfie to Anime

Generate anime-style face image.
based on pretrained model of https://github.com/margaretmz/Selfie2Anime-with-TFLite

Anime GAN

Transform photos into anime style images.
based on pretrained model of https://github.com/TachibanaYoshino/AnimeGANv2

MIRNet

Enhance low-light images upto a great extent.
based on pretrained model of https://github.com/sayakpaul/MIRNet-TFLite

2. How to Build & Run

2.1 setup environment

Download and install Android NDK.

$ mkdir ~/Android/
$ mv ~/Download/android-ndk-r20b-linux-x86_64.zip ~/Android
$ cd ~/Android
$ unzip android-ndk-r20b-linux-x86_64.zip

Download and install bazel.

$ wget https://github.com/bazelbuild/bazel/releases/download/3.1.0/bazel-3.1.0-installer-linux-x86_64.sh
$ chmod 755 bazel-3.1.0-installer-linux-x86_64.sh
$ sudo ./bazel-3.1.0-installer-linux-x86_64.sh

2.2 build TensorFlow Lite library and GPU Delegate library

run the build script to build TensorFlow Library

$ mkdir ~/work
$ git clone https://github.com/terryky/android_tflite.git
$ cd android_tflite/third_party/
$ ./build_libtflite_r2.4_android.sh

(Tensorflow configure will start after a while. Please enter according to your environment)


$ ls -l tensorflow/bazel-bin/tensorflow/lite/
-r-xr-xr-x  1 terryky terryky 3118552 Dec 26 19:58 libtensorflowlite.so*

$ ls -l tensorflow/bazel-bin/tensorflow/lite/delegates/gpu/
-r-xr-xr-x 1 terryky terryky 80389344 Dec 26 19:59 libtensorflowlite_gpu_delegate.so*

2.3 Download the needed assets

$ cd ~/work/android_tflite
$ ./download_all_assets.sh

2.4 Build Android Applications

Download and install Android Studio.
Start Android Studio.

$ cd ${ANDROID_STUDIO_INSTALL_DIR}/android-studio/bin/
$ ./studio.sh

Install NDK 20.0 by SDK Manager of Android Studio.
Open application folder (eg. ~/work/android_tflite/tflite_posenet).
Build and Run.

3. Tested Environment

Host PC	Target Device
x86_64	arm64-v8a

android_tflite's Issues

Blazeface tflite app references tflite_deeplab.h in the app_engine.h

The blazeface app build fails because it reference a tflite_deeplab.h.

Where can I find the deeplab header file, and how does the app use that code?

Please explain. Eagerly waiting.

clang++: error: linker command failed with exit code 1 (use -v to see invocation)

Hi guys,

I have to build tflite_age_gender but the bellow errors have occurred.

Using Front and Rear camera at the same time

Hi @terryky

I have been trying to get 2 cameras working at the same time. Looks like you have utilizes camera 2 api so it's possible. For some reason merely duplicating the pipeline to the srctex isn't working for a second camera.

I think the issue is with the hardware buffer. Or something only one camera works at a time. I think the pipeline to the srctex can be simplified to be available as an api. Could you give me some pointers, I have been stuck at it for a month now. Thanks!

Keypoints score

Why score of key points has negative values and also values over 1.0 ?
Here is printed values for a two keypoints before drawing a joint
float s0 = pose_ret->pose[pid].key[id0].score;
float s1 = pose_ret->pose[pid].key[id1].score;

also can you add script to generate arm .so file also ? with arm64

android tflite for face recognition using mobilefacenet

Hey, I wanted to integrate mobilefacenet based face recognition with the tflite blazeface app and I would like to know the steps and how I can achieve that using GPU and c++ implementation of tflite

Is there any introduce for training pipeline？

Using the face mesh tflite model from Mediapipe

Hi, Is there a way to add the face mesh tflite model from Mediapipe here? like you did with the hand landmark? Thank you.

DBFace using with Android tflite format

Hello,

I have a question about using the db_keras.tflite model in Android. I am not sure the correct parameters for the face detector when generating anchors. If you can provide info about them that would be amazing. Info that I am lacking are feature sizes & anchor sizes with anchor ratios, here I have added some random data from another object detector:

private static final int[] feature_map_sizes = new int[] {33, 17, 9, 5, 3};

private static final float[][] anchor_sizes = new float[][] {{0.04f, 0.056f}, {0.08f, 0.11f}, {0.16f, 0.22f}, {0.32f, 0.45f}, {0.64f, 0.72f}};

private static final float[] anchor_ratios = new float[] {1.0f, 0.62f, 0.42f};`

If u have pre-processing and post-processing for face detector in Android Java code that would help immensely. Thank you.

Can you please provide MIRNet for android?

possibility of integrating Camera2 API and OpenGL ES/Vulkan with tflite

Following repo does zero cpu copy and processes frame directly on gpu.

https://github.com/ochornenko/Camera2GLPreview

Since your implementation is also on gpu, can we expect integration with vulkan and camera2 pipeline with tflite
