2022年4月21日 · A JP2 file is a compressed bitmap image saved in the JPEG 2000 (JP2) Core Coding format. It supports any color bit depth and image metadata and may be compressed with lossy or lossless compression. Users often save digital photos and medical images, such as CT and MRI scans, as JP2 files.

JPEG 2000 (JP2) is an image compression standard and coding system. It was developed from 1997 to 2000 by a Joint Photographic Experts Group committee chaired by Touradj Ebrahimi (later the JPEG president), [ 1 ] with the intention of superseding their original JPEG standard (created in 1992), which is based on a discrete cosine transform (DCT ...

JPEG 2000 是基于 小波变换 的 图像压缩 标准，由 聯合圖像專家小組 创建和维护。 JPEG 2000曾獲认为是未来取代 JPEG （基于 离散余弦变换）的下一代图像压缩标准。 JPEG 2000文件的副檔名通常为.jp2， MIME类型 是 image/jp2。 JPEG 2000的压缩比更高，而且不会产生原先的基于离散余弦变换的JPEG标准产生的塊狀模糊瑕疵。 JPEG 2000同时支持 有损数据压缩 和 无损資料壓縮。 另外，JPEG 2000也支持更复杂的渐进式显示和下载。 JPEG 2000是国际标准化组 …

JPEG 2000 (JP2) is an image coding system and state-of-the-art image compression standard. It use wavelet technology to code lossless content in any quality at once.

Sample JP2 files are pre-created images in the JPEG 2000 (JP2) format, which is a modern image compression standard designed for high-quality image storage. The JP2 format supports both lossless and lossy compression, allowing for efficient storage without significant loss …

2024年4月25日 · What is a JP2 file? A .JP2 file is a JPEG 2000 Image file. Files that contain the .jp2 file extension normally store compressed bitmap images. The JPEG2000 Core Coding System uses a wavelet compression algorithm instead of the common DCT compression method that is used with standard JPEG images.

JPEG 2000 (JP2) 是一种图像编码系统和最先进的图像压缩标准。 它使用小波技术一次编码任何质量的无损内容。 此外，在编码效率没有任何实质性损失的情况下，JPEG 2000 能够有效地访问相同的内容并将其解码为各种其他分辨率和质量。 JPEG 2000 中的码流具有显着的可扩展性，具有为空间随机访问提供便利的感兴趣区域。 JPEG 2000 是最具可扩展性的标准之一。 可以使用不同的质量存储图像的不同部分。 通过以多种方式对码流进行排序，可以实现显着的性能提升。 …
