Is it possible to do panorama Image Stitching in Android from Java?

由 一笑奈何 提交于 2019-12-07 18:48:33
问题 I am using openCV4Android and I know there are lots of questions related with this topic. Most of them (the ones with answer), suggest a solution with C++ and add it to the project in the folder jni + Android.mk, etc. Can I do something to avoid C++ and call every method from Java? If it is not possible with OpenCV, I am open to try alternatives. Thanks. 回答1: There is a JavaCV - Java interface to the OpenCV library, it is popular for the Android application. 回答2: You will need to use JNI NDK

问题 I am quite new in image stitching techniques and algorithms. What I need is to stitch several images (from 2 to 20). Image size is around 4-5 MB and resolution is 4000x3000. Since I have .NET background I tried EmguCV stitching sample application that goes with installation package. But all the time I am getting OutOfMemory exception or failed to allocate xxxxx bytes. After that I tried write native C++ console application that is using OpenCV and got same results. So problem is inside

Is stitching module of OpenCV able to stitch images taken from a parallel motion camera?

问题 I was wondering if the stitching(http://docs.opencv.org/modules/stitching/doc/stitching.html) module of OpenCV is able to stitch the images taken from a camera that is in parallel motion to the plane which is being photographed ? I know that generally all the panoramic stitching tools assume that the center of the camera is fixed and that the camera only experiences motion such as pan or pitch. I was thinking if I can use this module to stitch the image taken from a camera which moves

Panorama stitching for text

问题 I'm looking for a good panorama stitching library for text. I tried OpenCV and OpenPano. They both work good on regular photos, but fail on text. For example I need to stitch the following 3 images: The images have about 45% overlapping between each other. If there's an option to make one of the mentioned libraries work good on text images, instead of finding another library, that would be great. I need the library to work on linux arm. 回答1: OpenPano fails at stitching text because it cannot

stitch images together in python

I am trying to stitch about 50 images(all in the same 287x287 size) together. Specifically, there should be 25 images on the top row and 25 images on the bottom row, and there also exists a small distance between each two images. I met two difficulties during my attempts: First problem is that there are 25 images in a folder with their name 'prefix-70',...,'prefix-94' while other 25 images in another folder with the same name 'prefix-70',...,'prefix-94' . I do not know how to them in Python without conflicts. Second problem is that I wrote the following code to read one folder images to form a

How can I optimize Multiple image stitching?

问题 I'm working on Multiple image stitching in Visual Studio 2012, C++. I've modified stitching_detailed.cpp according to my requirement and it gives quality results. The problem here is, it takes too much time to execute. For 10 images , it takes around 110 seconds . Here's where it takes most of the time: 1) Pairwise matching - Takes 55 seconds for 10 images! I'm using ORB to find feature points. Here's the code: vector<MatchesInfo> pairwise_matches; BestOf2NearestMatcher matcher(false, 0.35);

Panorama stitching with Android camera source code

问题 I'm trying to create a panorama image by stitching a set of bitmaps. For this task I'm using the source code from the android stock camera, which has a Panorama (mosaic) set of classes. This code can be found in many repositories, but in any case here is the official one: https://android.googlesource.com/platform/packages/apps/Camera2/+/android-4.4.3_r1 For users that are familiar with the stock android camera, the panorama option works by panning/moving the camera which automatically

I am doing image stitching in OpenCV (A panorama) but I have one problem. I can't use the class Stitching from OpenCV so I must create it with only feature points and homographies. OrbFeatureDetector detector( minHessian ); std::vector<KeyPoint> keypoints_1, keypoints_2; Mat descriptors_1a, descriptors_2a; detector.detect( img_1, keypoints_1 , descriptors_1a); detector.detect( img_2, keypoints_2 , descriptors_2a); //-- Step 2: Calculate descriptors (feature vectors) OrbDescriptorExtractor extractor; Mat descriptors_1, descriptors_2; cout<<"La distancia es " <<endl; extractor.compute( img_1,
