* Added implementation files for image_resize and resize_bicubic ops. * Image resize and image.resize_bicubic ops implementation. Initial revision. * Finished with infrastructure development for image.resize_bilinear op and image_resizo op implementation. * Refactored resize methods. * Added processing for Mitchelcubic algorithm. * Added check for input/output sizes. * Added int and float types for crop_and_resize op. * Refactored crop_and_resize output type check. * Added helper for bicubic interpolation as TF v.1 does. * Added TF v.1 bicubic helper for cuda platform. * Added cached class for bicubic algorithm. * Refactored cuda implementation for crop_and_resize helper to use proper output type. * Added facilities for bicubic interpolation. * Portion bicubic interpolation from TF. * Added tests for resize_bilinear testing. * Working implementation of bicubic interpolation and tests. * Refactored routines with image_resize bicubic op helper. * Refactored code with coding standards. * Refactored cpu helpers for resize_bicubic op. * Refactored bicubic helpers. * Added bicubic resize facilities. * Implementing cuda kernels for bicubic interpolation. Implementation step. * Cuda implementation of resize_bicubic op helper. * Refactor image.resize_bicubic op helpers. * Refactored helpers for resize_bicubic. Added error checking with cuda implementation. * Refactored cuda implementation of resize_bicubic op helper. The first working revision. * Cuda arch implementation for resize_bicubic op helper. Full working single-threaded revision. * Intermediate bicubic interpolation helper for cuda. * Refactored cpu helper for resize_bicubic. * Multithreaded cuda implementation for resize_bicubic. * Fixed merge issues. * Refactored nlp helpers. * Replicated resize_bicubic for 3D also. * Eliminated waste comments of unused code. * Eliminated waste comments with unused code. * Eliminated waste template definitions. * Eliminated waste debug code. * Eliminated waste comments. * Fixed multithreading with helpers. * Fixed test suites for float and double in float point input lists. * Fixed usage of reshape with 3D/4D on resizes. * Final fixes. * Fixed resize_neighbor op problem.
