How danielesavino/imageflow works

ImageFlow is a C image-processing library. An application loads an image, builds an operation flow, and runs it through a selected scheduler; the scheduler may reorder operations, dispatch implementations to available devices, and manage transfers before the result is stored. The graph preserves the documented CPU, CUDA, HIP, image-I/O, and scheduler capabilities. Several runtime relationships are documented in the README but their implementation bodies were not sampled, so those edges cite the README.

Main entry points: scheduler.c Scheduler dispatch · operations.c Operation dispatch · devices.c Device registry · img_loader.h Image transfers
