+# Sample Applications
+
+<a href="https://www.khronos.org/openvx/" target="_blank">Khronos OpenVX™</a> is an open, royalty-free standard for cross-platform acceleration of computer vision applications. OpenVX enables performance and power-optimized computer vision processing, especially important in embedded and real-time use cases such as face, body, and gesture tracking, smart video surveillance, advanced driver assistance systems (ADAS), object and scene reconstruction, augmented reality, visual inspection, robotics and more.
+
+In this project, we provide samples that use our optimized libraries to build applications that showcase potential usage or may used as reference to develop your own products.
+
+## Bubble Pop
+
+In this sample we will create an OpenVX graph to run Bubble Pop on a live camera. This sample application uses <a href="https://en.wikipedia.org/wiki/OpenCV" target="_blank">OpenCV</a> to decode input image, draw bubbles/donuts and display the output.

+

+
+### Prerequisites
+
+* [Conformant OpenVX Implementation](https://github.com/KhronosGroup/Khronosdotorg/blob/master/api/openvx/resources.md)
+
+* [OpenCV](https://github.com/opencv/opencv/releases/tag/3.4.0)
+
+* Camera
+
+### Steps to run the Bubble Pop sample
+
+* **Step - 1:** Build and install [Conformant OpenVX Implementation](https://github.com/KhronosGroup/OpenVX-sample-impl). In this example we will use the OpenVX Sample Implementation available on [GitHub](https://github.com/KhronosGroup/OpenVX-sample-impl)
+
+```
+Build OpenVX on Linux
+
+* Git Clone project with a recursive flag to get submodules
+
+      git clone --recursive https://github.com/KhronosGroup/OpenVX-sample-impl.git
+
+* Use Build.py script
+
+      cd OpenVX-sample-impl/
+      python Build.py --os=Linux --arch=64 --conf=Debug --conf_vision --enh_vision --conf_nn
+```
+
+* **Step - 2:** Export OpenVX Directory Path
+
+```
+export OPENVX_DIR=$(pwd)/install/Linux/x64/Debug
+```
+
+* **Step - 3:** Clone the OpenVX Samples project and build the bubble pop application
+
+```
+cd ~/ && mkdir OpenVXSample-pop
+cd OpenVXSample-pop/
+git clone https://github.com/kiritigowda/openvx-samples.git
+```
+
+* **Step - 4:** CMake and Build the pop application
+
+```
+mkdir pop-build && cd pop-build
+cmake -DOPENVX_INCLUDES=$OPENVX_DIR/include -DOPENVX_LIBRARIES=$OPENVX_DIR/bin/libopenvx.so ../openvx-samples/bubble-pop/
+make
+```
+
+* **Step - 5:** Run VX Pop application
+
+    * **Bubbles**
+
+    ```
+    ./vxPop --bubble
+    ```
+
+    * **Donuts**
+
+    ````
+    ./vxPop --donut
+    ````
