At least one activity is always present which is known as MainActivity. It starts when the application is launched. These can be one or more depending upon the App. In other words, it is a User Interface that contains activities. The four major app components are:Īctivities: It deals with the UI and the user interactions to the screen. Some of these components depend upon others also. Each component has its own role and life cycles i.e from launching of an app till the end. The App components are the building blocks of Android. The XML file deals with the design, presentation, layouts, blueprint, etc (as a front-end) while the JAVA or KOTLIN deals with the working of buttons, variables, storing, etc (as a back-end). In Android, basically, programming is done in two languages JAVA or C++ and XML(Extension Markup Language).

Here is a code sample that shows grabbing the image preview size, converting to RGB, grabbing a matrix of the result, and applying this to create a bitmap that can be used for processing. In the Android code examples here, you will see that the image data is converted from YUV to RGB. ColorspaceĮach camera hardware/software platform can treat color and colorspace differently, so that when you are reading the information from the camera, realize that this information needs to be conformed to one common standard before sending it forward for detection in Caffe2. You will may notice that it is referred to 224x224x3, the first two being height and width, and the last part (3 for RGB) referring to the colorspace, which brings us to our next very important topic. In this example we also resize the image to 224 x 224. Keep in mind that as part of the processing for Caffe2, images should be square, so that even if the camera takes a 16:9 or other non-square image and passes that into the detection flow, it will need to be resized to be square. The name of the object will be shown along with the probability result - how much the model believes the object matches with the similar object that was in its training dataset. Detection time can suffer a little as well, so as you work on your own models you will want to analyze the tradeoffs of accuracy, range, size, and speed. We will use a pre-trained model that was built from a database of 1000 objects. In this example we are going show very fast object detection that can be used after an image is taken or in real-time while the camera is in its viewer mode. Below we provide instructions for building with Android Studio.

Install your IDE of choice or be prepared to build manually. In this recent announcement of Facebook’s updated camera features, many of the effects, including style transfer can be attributed to Caffe2. Caffe2 is powering some of the coolest advances in mobile applications, especially for the camera.
