최근에 정지 홀로그램에 대한 표준화 및 압축 방법에 대한 연구를 JPEG Pleno에서 진행 중에 있다. 또한, 기존 연구들에서 웨이블릿 변환의 효율이 좋은 대안이 될 수 있다는 것을 보여왔다. 웨이블릿 변환기반의 압축에서 EZW, EBCOT 그리고 SPIHT 등을 사용할 수 있다. 하지만 부대역 단위의 제로트리 기반의 알고리즘들은 고해상도의 영상에 대해서 고압축으로 코딩할 경우에 비트스트림 제어 시 악영향을 줄 수 있으며, EBCOT는 지나치게 복잡도가 높다. 이를 보완하기 위해 본 논문에서는 홀로그램의 압축을 위해 양자화된 웨이블릿 트리를 사용하여 압축하는 방법을 제안한다. 양자화 트리는 해당 홀로그램의 대표 계수 값을 양자화하여 획득한다. 양자화 트리를 사용하여 양자화한 후에 원본과의 차이 값을 SPIHT를 통해 압축하여 목표 BPP에 맞게 압축한다.
