Using patches for parallelization in high-resolution signal compression has some potential drawbacks:
Block Artifacts: Dividing high-resolution signals into patches may introduce block artifacts at patch boundaries due to discontinuities between neighboring regions during reconstruction.
Information Discrepancies: Information content across patches may vary significantly, leading to challenges in allocating bits optimally among different regions when compressing each patch independently.
Complexity Management: Managing multiple smaller INRs for individual patches adds complexity to training and optimization processes, potentially requiring additional computational resources and careful tuning of hyperparameters.
Loss of Global Context:
Splitting data into patches may result in loss of global context information crucial for accurate reconstruction, especially when dependencies exist across different parts of the signal.
