Alexander Alekhin	c49d5d5252	core: fix pthreads performance OpenCV pthreads-based implementation changes: - rework worker threads pool, allow to execute job by the main thread too - rework synchronization scheme (wait for job completion, threads 'pong' answer is not required) - allow "active wait" (spin) by worker threads and by the main thread - use _mm_pause() during active wait (support for Hyper-Threading technology) - use sched_yield() to avoid preemption of still working other workers - don't use getTickCount() - optional builtin thread pool profiler (disabled by compilation flag)	7 years ago

Alexander Alekhin	cec700525c	core(ocl): fix deadlock in UMatDataAutoLock UMatData locks are not mapped on real locks (they are mapped to some "pre-initialized" pool). Concurrent execution of these statements may lead to deadlock: - a.copyTo(b) from thread 1 - c.copyTo(d) from thread 2 where: - 'a' and 'd' are mapped to single lock "A". - 'b' and 'c' are mapped to single lock "B". Workaround is to process locks with strict order.	7 years ago

SarenT	c6d9ce8fd3	Merge pull request #10489 from SarenT:offset-mat_put 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	7 years ago

Jun Zhao	0369431ebd	opencl/cvtclr_dx: fix not compile-time constants issue. fix the "initializing global variables with values that are not compile-time constants" issue in Intel SDK for OpenCL. The root cause is when initializing global variables with value, the variable need is compile-time constants.

Arjan van de Ven	fc8e848a54	Add basic plumbing for AVX512 support The opencv infrastructure mostly has the basics for supporting avx512 math functions, but it wasn't hooked up (likely due to lack of users) In order to compile the DNN functions for AVX512, a few things need to be hooked up and this patch does that Signed-off-by: Arjan van de Ven <arjan@linux.intel.com>	7 years ago
