Adding capability to parse subsections of a byte array in Java bindings (#10489)
* Adding capability to parse subsections of a byte array in Java bindings. (Because Java lacks pointers. Therefore, reading images within a subsection of a byte array is impossible by Java's nature and limitations. Because of this, many IO functions in Java require additional parameters offset and length to define, which section of an array to be read.)
* Corrected according to the review. Previous interfaces were restored, instead internal interfaces were modified to provide subsampling of java byte arrays.
* Adding tests and test related files.
* Adding missing files for the test.
* Simplified the test
* Check was corrected according to discussion. An OutOfRangeException will be thrown instead of returning.
* java: update MatOfByte implementation checks / tests
Previous commit, 6f39f9a, tries to fix the color issue for emulator. But the condition for detecting emulator is incomplete, e.g. it stops working for emulators using Google Play, whose Build.BRAND=="google". https://stackoverflow.com/a/21505193 shows a more accurate condition for this.
* Introduced OSGi Blueprint XML file and Bean class too automatically load the native library.
* Introduced integration testing module to deploy to Karaf OSGi implementation.
* Clears library executable stack flag during build.
* Updated README document.
* Adds the main features2d header to the parse list for the generator.
* Removes the manual definition of drawKeypoints and drawMatches since these are now included in the main header.
* Updates the generator to ignore SimpleBlobDetector, FlannBasedMatcher and DescriptorMatcher as these cause conflicts with the generator. This is okay since these were not previously included in the distribution anyway, so no harm is done.
- cv2.UMat implemented - python thin wrapper for UMat
- no implicit copy from GPU to Host done, resulting UMat can be passed to next function without overhead
- cv2.UMat.get() - to fetch data to Host
- new tests covers: ORB, BFMatcher, goodFeaturesToTrack, calcOpticalFlowPyrLK
