摘要

提出了一种新的全光域图像压缩方法。新的硬件架构适合与数码相机直接集成进行图像处理。该架构基于光学Haar小波变换(HWT)，仅使用一个4x4多模干涉(MMI)耦合器级联一个2x2 MMI耦合器。因此，图像的处理速度非常快。

On-chip All-optical Haar Transform based on a 4x4 MMI coupler cascaded with a 2x2 MMI coupler for Image Compression

We present a new method for image compression in all-optical domain. The new hardware architecture is suitable for directly integrating with digital cameras for image processing. The proposed architecture is based on the optical Haar wavelet transform (HWT) using only one 4x4 multimode interference (MMI) coupler cascaded with a 2x2 MMI coupler. The processing of images therefore is at very high speed.
