captureWebcamImage

Acquires an image (in fact an RGB image stack with three slices) of given size using a webcam.

It uses the webcam-capture library by Bartosz Firyn.https://github.com/sarxos/webcam-capture

Availability: Available in Fiji by activating the update sites clij and clij2. This function is part of clijx_-0.32.0.1.jar.

Usage in ImageJ macro

Ext.CLIJx_captureWebcamImage(Image destination, Number cameraDeviceIndex, Number imageWidth, Number imageHeight);

Usage in object oriented programming languages

Java

// init CLIJ and GPU
import net.haesleinhuepf.clijx.CLIJx;
import net.haesleinhuepf.clij.clearcl.ClearCLBuffer;
CLIJx clijx = CLIJx.getInstance();

// get input parameters
destination = clijx.create();
int cameraDeviceIndex = 10;
int imageWidth = 20;
int imageHeight = 30;

// Execute operation on GPU
clijx.captureWebcamImage(destination, cameraDeviceIndex, imageWidth, imageHeight);

// show result
destinationImagePlus = clijx.pull(destination);
destinationImagePlus.show();

// cleanup memory on GPU
clijx.release(destination);

Matlab

% init CLIJ and GPU
clijx = init_clatlabx();

% get input parameters
destination = clijx.create();
cameraDeviceIndex = 10;
imageWidth = 20;
imageHeight = 30;

% Execute operation on GPU
clijx.captureWebcamImage(destination, cameraDeviceIndex, imageWidth, imageHeight);

% show result
destination = clijx.pullMat(destination)

% cleanup memory on GPU
clijx.release(destination);
