vertex coordinates
1.2 patch (FACE)
Patches in mesh meshes are triangles with a special face class description, and the face class records the index of a patch's three vertices in the vertex array, the visibility of three edges, the visibility of the polygon, the smoothing group to which it belongs, and the associated material ID. In the mesh class, the patch array is faces, which is an array of face types, and the array length is determined by me
the coordinate system in this transformation. In Android, the default view coordinate system is the upper-left vertex (0, 0), the x-axis, and the y-axis. This requires that the rect coordinate be transformed. Another difficulty is that this face detection must be started after the camera is turned on, and if you take a photo or stop the preview, you need to activate it again. You need to add a delay when activating, otherwise it won't work.In addition, still have to explain, in the preview scre
Developers believe that if appropriate tools are available to create interactive web interfaces, they can focus their time on core requirements and customization, and deliver applications in a timely manner within the specified time. Compared with other technologies such as assumerver pages or Apache struts, The assumerver faces (JSF) technology facilitates the creation of interactive web applications. JSF draws a clear line between Program Logic and
Two classes are frequently used in the faces API. One is facescontext and the other is externalcontext. First, we will explain how to use facescontext.
For each JSF request, the facesservlet object obtains a javax. Faces. context.An instance of the facescontext class. The facesservlet object transmits the following three objects from the Web container to the getfacescontext method of the javax.

Two important presentation layer technologies of J2EE: JSP and JSF released a preview version of the new technology specification. The most important thing is that the two adopt the Expression Language (EL) partially merged into one. In the near future, these two technologies may be further integrated to form a unified presentation layer technology. However, in the general view of the J2EE community, JSP is not the best choice if it is just a view technology. template-based view technologies suc

We can use an icon (including Jbutton,jcheckbox,jradiobutton and different types of jmenuitem) in a jlable or anything inherited from AbstractButton. Using the Jlables icon is very easy (we'll see it in a subsequent program example). The following program example explores all the other ways that we can take advantage of button icons and their derivatives. We can use any GIF file we need, but the GIF file used in this example is part of the book's coded release and can be downloaded at www.Bruce
brightness and contrast of facial images. To get better results, you can use color face recognition (color faces recognition,ideally with color histogram fitting in HSV or another color space instead of RGB), or use more preprocessing, such as edge enhancement, contour detection (contour detection), gesture detection (motion detection), and so on.You can see an example of a preprocessing phase:

The facial detection feature is not supported on all devices. You can call getMaxNumDetectedFaces () to check whether it is supported.
To receive and respond to face detection notifications, you must set a listener for face detection events in your camera application. therefore, you must create a listener class to implement Camera. the FaceDetec
