This is the + get_next_double_click() routine. + - Added svd_fast() + - Added cca() + - Added serialization support for std::vector<bool>. + - Added make_sparse_vector_inplace() + - added the orthogonalize() function. + - Added count_bits() and hamming_distance() + - Added parallel_for() and parallel_for_blocked() + - Added cosine_distance and negative_dot_product_distance + - Added an operator>> for matrix objects which allows you to read in ASCII + matrices using the format used by operator<<. + - Added average_precision() Non-Backwards Compatible Changes: + - Changed ranking evaluation functions to return the mean average precision + in addition to just raw ranking accuracy. This changes their return types + from double to matrix<double,1,2>. + - Generalized segment_image() so it works on any pixel type or array of + vectors. I also changed it's interface slightly. In particular, I removed + the min_diff parameter and replaced it with an explicit min_size parameter. Bug fixes: + - Fixed an endianness bug in the PNG I/O functions which occurred when 16bit + grayscale PNGs were used. libpng doesn't automatically convert from host + endianness to big endian as the PNG standard demands. You have to explicitly + tell it to do this or it will write out the 16bit pixel data in host order + which result in the wrong thing happening on little endian chips. Similarly + for reading PNGs. + - Fixed a bug which could potentially occur when empty std::vector<char> or + std::vector<unsigned char> were serialized. + - There was a bug in the version of draw_line() that draws directly onto an + array2d type image (not the one that draws onto a GUI canvas object). The + bug triggered whenever a perfectly horizontal or vertical line that extended + outside the image was drawn. This has been fixed. + - Fixed a bug in the Windows implementation of the signaler object, which + was found by Isaac Peterson. The bug caused the program to deadlock if + signal() or broadcast() was called at exactly the same time a + wait_or_timeout() function timed out. + - Fixed a bug in the image_window and image_display GUI tools which caused + them to not redraw overlay lines correctly in certain cases involving + non-default zoom levels. + - Switched randomly_color_image() to use the non-pointer based version of + murmur_hash3() to avoid violation of the strict aliasing rule. In + particular, the previous version didn't work correctly in gcc 4.7.2 when + optimizations were enabled. Other: + - Refactored the Platt scaling code a little. Now there is a function, + learn_platt_scaling(), that allows you to directly call the Platt scaling + code without supplying a trainer object. + - Optimized the oca and structural SVM solvers. They are now a little bit faster + than in previous dlib releases. + - Changed how the SURF descriptor is computed slightly to improve its accuracy.
