Sparse point spread function-based multi-image optical encryption

Sparse point spread function-based multi-image optical encryption

Abstract Multi-image optical encryption (MOE) has demonstrated promising potential in image data protection owing to its parallel processing capability and abundant degrees of freedom. However, existing methods suffer from either low compression ratios or stringent experimental conditions, such as a...
