![]() Notice the Main() method calls run() which use an awt.Image type as an input parameter. Start exploring the examples by viewing the developer comments in the file src/publication/SobelFilterExample.java. (To see this menu right click the project and choose Properties › Java Build Path › Libraries.) 2011-opencl-00.pngįinally, ensure that the platform specific files are exported: 2011-opencl-02.png For example notice that the file is referenced in the project. Then ensure that the platform specific jar is exported during the project build. Notice the below example where the libgluegen-rt.dylib, libJOCL-apple-x86_64.dylib, and libjocl.dylib files are in the platform specific directory. dll) into the parent directory if they are not already present. You need to unzip each of the three jar files and copy the dynamic files (.so. If you look in the lib folder, you will find -natives-xyz.jar files containing the respective libraries. Understanding platform-specific JOCL native librariesįor these samples, three native libraries are needed: gluegen-rt, jocl, and JOCL-‘platform’-‘arch’. Since each OS has different native JOCL native libraries, the runtime environment must be configured such that the Java code can load the needed native libraries. The OpenCL code you write can also leverage JOCL to accelerate execution of ImageJ plugins from Java. JOCL uses JNI to make calls into the OpenCL API. To use OpenCL from Java in ImageJ we leverage JOCL. We have included the necessary JOCL native libraries for Windows 32/64, Apple, and Linux 32/64 platforms inside this directory. lib - libraries needed for classes using JOCL, ImageJ, and Hessian 4.0.7. ![]() sourcedata - (Point Spread Function) PSF and 3D data used as a small sample data set for the FHT3D Example.Note: Runtime compilation of the OpenCL source files allows execution on any potential OpenCL enabled device. When executed, the Java code in provided in the examples compile these the OpenCL for execution. cl) Notice the files fht.cl and sobel.cl in the src directory. src - Java and OpenCL source files (extension.The folder structure of the source consists of the following: Import the branch and assign a general project name like imagej-opencl. Here are the steps for setting up Ubuntu: Mac OS X 10.6, Windows 64/32, and Linux 64/32 pass the tests and are supported by this package. We set up an Ubuntu based development machine for OpenCL development and testing. We have created an OpenCL deconvolution example to demonstrate compute acceleration using OpenCL (both locally and remotely as a binary web service). JOCL is written on top of a low level JNI API to make using OpenCL a bit easier. To use OpenCL from Java in ImageJ we rely on JOCL. This tutorial is meant to help you leverage OpenCL from Java for use with ImageJ. A potential alternative for using OpenCL in ImageJ is CLIJ. This tutorial was written in 2010-11, and contains out-of-date or no-longer-accurate information.
