This pull request introduces a new mask erosion utility to the AliceVision project, enabling users to process binary mask images by eroding their valid regions. The main changes add the
aliceVision_maskErodingcommand-line tool, integrate it into the build system, and expose it as a node in the Meshroom pipeline.New mask erosion feature:
aliceVision_maskErodingcommand-line tool for eroding binary mask images, including implementation of the mask erosion algorithm using integral images and parallel processing (src/software/utils/main_maskEroding.cpp).Build system integration:
aliceVision_maskErodingtool in the CMake build system, ensuring it is built and linked with the required dependencies (src/software/utils/CMakeLists.txt).Meshroom node integration:
MaskErodingthat wraps the mask erosion functionality, defines its inputs/outputs, and exposes parameters such as erosion radius and verbosity (meshroom/aliceVision/MaskEroding.py).
