22 | ## Details
23 |
24 | You essentially have to override an onPreviewFrame(byte[] data, Camera cam) method and convert from the default YUV to RGB:
25 |
26 | int[] rgb = ImageProcessing.decodeYUV420SPtoRGB(data, width, height);
27 |
28 | Create an object which you'll use for motion detection code:
29 |
30 | IMotionDetection detector = new RgbMotionDetection();
31 |
32 | Call the detect() method passing in the parameters obtained above.
33 |
34 | boolean detected = detector.detect(rgb, width, height)
35 |
36 | If the boolean "detected" variable is true then it has detected motion.
37 |
38 | The RGB detection code is located in RgbMotionDetection.java class. The image processing code is located in ImageProcessing.java static class. The Activity to tie it all together is in MotionDetectionActivity.java.
39 |
40 | I have created a MotionDetection class that detects motion comparing RGB values called RgbMotionDetection.java, a class that detects motion comparing Luminance values called LumaMotionDetection.java, and a class that detects motion comparing avergae Luminance values in regions called AggregateLumaMotionDetection.java.

This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.
67 |The Overview page is the front page of this API document and provides a list of all packages with a summary for each. This page can also contain an overall description of the set of packages.
73 |Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain four categories:
77 |Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:
89 |Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.
109 |Each annotation type has its own separate page with the following sections:
113 |Each enum has its own separate page with the following sections:
124 |There is a Class Hierarchy page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with java.lang.Object. The interfaces do not inherit from java.lang.Object.
The Deprecated API page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.
142 |The Index contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.
146 |These links take you to the next or previous class, interface, package, or related page.
150 |These links show and hide the HTML frames. All pages are available with or without frames.
154 |Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description.
158 |The <a href="constant-values.html">Constant Field Values</a> page lists the static final fields and their values.
