android camera image recognition

Simple to do a camera and picture editing module, time reason very versatile has not been done. There are still bugs, forgive, will be in the future to change the timeCode addressPS: Please order a star^-^--------------------------------------------------------------------------------------------------------------- --Brief introduction:1.

Android Camera Real-Time Filter (5), androidcameraAndroid static filter implementation 1. Review knowledge point 1. Basic filter effect implementation (black and white filter) The technology used is ColorMatrix. The image imaging effect is changed by changing the RGBA coefficient. Created with Rapha rjl 2.1.2

Because the decode out of the picture is too small, smaller than the screen. As a result, the image is magnified slightly when displayed, causing the line shape to appear jagged.Ability to change the size of the Getscreenimagesize method, for example, to make 133, larger.Detailed changes such as the following:Modify Getscreenimagesize function in Filtershowactivity.java file about lines 507.private int getscreenimagesize () {Displaymetrics metrics = n

In the development of Android often use the image upload function, commonly used is to call the Android system comes with the library and photo function. The sample code is as follows:Java code:public class Testactivity extends Activity {public final static int photo_zoom = 0; Public final static int take_photo = 1; Public final static int photo_result = 2;

is as follows: [Java] Public void onDrawFrame (GL10 gl ){// TODO Auto-generated method stubGl. glClear (GL10.GL _ COLOR_BUFFER_BIT | GL10.GL _ DEPTH_BUFFER_BIT );MTriangle. draw (gl );}Public void onDrawFrame (GL10 gl ){// TODO Auto-generated method stubGl. glClear (GL10.GL _ COLOR_BUFFER_BIT | GL10.GL _ DEPTH_BUFFER_BIT );MTriangle. draw (gl );} In this way, we have drawn a plane triangle. However, we found that this triangle is not an equilateral triangle as we defined it. This is because O

Therefore, you must add a processing method to the onactivityresult method,

Recently called the camera in the project, the use of someone else to write the file, but found that the captured photos did not really use the system photography and then view so clear, so the study, found that the usual call camera function to obtain the image is compressed, if you want to get the original picture, it has to be saved after the acquisition. Find

Implementation of Camera Real-Time Filter on Android platform (7) -- Basic filter creation method (1) Regarding how to make filters, zhihu's top ticket in this Q A gave a professional answer In addition, InstagramFilters, an open-source project of githunb, once provided some filter code of the first version of Instagram, which is less than 20 types. GPUImage also has some

There are 3 ways to get pictures, one is to use the surface control, using the lens to obtain the picture, and the second is to call the system camera, and return the pictures taken; third, directly in the use of the library to obtain local images; Here I only use the following two methods to get the picture (the system provides a method, why not? It will take so much effort to develop a new function that has already been made, not to reinvent the whe

Let's start with the round effect of the snap button. Android development, of course, can find artists to design pictures, and then directly brought in. It's just that we can write our own code to achieve this effect. The most commonly used is to use the layout-list implementation of the image overlay, our layout named Btn_take_photo.xml, which is a self-defined drawable file, so according to the specificat

finally gets a darker image. This pattern is symmetric, which means that the exchange base and the blend color get the same result.F (b) = AB, where a is the base color and B is a blend color.Filter--First, the pixel values of the two-layer images are complementary, then multiply them, and finally the complementary number. This is the opposite of the result from the multiply. It will get a brighter image.F (b) =1-(1-a) (1-b), where a is the base colo

Implementation of Camera Real-Time Filter on Android platform (9) -- Exploring skin polishing algorithm (1) The previous article mentioned some de-noise algorithms that can be used for skin polishing. Below we will implement these algorithms and observe the results, so we will not consider the real-time issue. First, this article discusses "Image Denoising Based

System camera call method: Step 1: Intent bycamera = new intent ("android. Media. Action. image_capture"); bycamera. putextra (mediastore. extra_output, Uri. fromfile (yourfilepath); startactivityforresult (bycamera, 0 ); Step 2: Obtain the returned data in the onactivityresult (INT, Int, intent) method of the current activity. Protected void onactivityresult (INT requestcode, int resultcode, i

[Android] takes a photo, saves it, and displays it in the ImageView control. Recently, I am working on Android projects, some of which involve image processing content. the following describes how to call the Camera application to take a photo and save it in the ImageView control.PS: The author purchased the first line
