android camera image recognition

As a reference for implementing image recognition at the Java layer. We recommend that you use the JNI layer to extract data. -- Leon Http://blog.csdn.net/chenji001/archive/2010/08/25/5836685.aspx In Android, if you want to process preivew data (such as face tracking), the callback function at the Java layer will cause frequent memory application and cop

Capturing images using the built-in camera applicationAll original Android devices with the right hardware (webcam) will come with the camera application. The camera application contains an intent filter (Intent Filter) that enables developers to provide the same image captu

At present, almost all of the apps in the user registration will have the need to set the avatar, roughly divided into three kinds of situations:(1) by acquiring a picture of a local photo album, it is cropped as an avatar.(2) by starting the phone camera, now shoot the picture and then cut it as the avatar.(3) In the app to add some of their own avatar resources for users to choose (not human-friendly, currently rarely used).This time, we briefly int

to know the length and width of the desired image in advance. For example, I want to cut an image of 400*400 (unit: px. Use this as a benchmark to calculate the length and width of the Rect displayed on the screen, and then draw the MaskView. Select the mode as needed. This article uses the first mode as an example. The code below: Package on the basis of the miscellaneous documents. First, encapsulate a M

Introduction The Matrix of Android deformation (Transform) is used to summarize the use of Camera. Camera mainly implements 3D deformation, rotation, rotation, etc. The source code of Camera is Native (Local Code) the provided interfaces are also relatively simple. Official introduction: A

During Android development, it takes most of the time to create the interface, and only developers can make it by themselves. Therefore, I have been trying to use HTML5 + css3 to complete the process. phonegap is not quite mature yet, I am going to use Android native + webview to complete the process. I found that it is similar to flash as for mutual debugging. BelowCodeThe Native Interface is called throug

When the zc301 USB camera is used, the camera returns a JPEG image. The preview of camera requires JPEG decoding (not done), but you can take the JPEG image directly. 1. Modify Your boardconfig. mkUse_camera_stub: = false Set stub to false, and do not compile in android2.1/f

If there are no new requirements for the system, direct calls are the most direct. The following describes how to call a system camera to take pictures and save images and call a system album. First, let's take a look at the core method of calling the System camera: Intent camera = new Intent (MediaStore. ACTION_IMAGE_CAPTURE); startActivityForResult (

To do a program ape has a period of time, things have done a lot, today just opened a blog, I have done before the record down, today first write Android system down with the system camera and cutBefore making a call to the system camera has encountered a lot of problems, and now paste code, in the code to put a littleBtn.setonclicklistener (New Onclicklistener (

In android, the camera function system has been provided and can be directly used in apps.

This camera is not a camera in Android. the camera in the graphics package can be understood as the angle of view in the 2D graphics system, or the camera location. Based on the perspective principle, we can implement some simple 3D effects. You can refer to the rotate3danim

Someone would say that it's possible to use a webcam with a OpenCV under Linux, but I didn't do it, and I did it in the most primitive Way (V4L2). Before the
