解压缩小波压缩图像

[英]uncompress wavelet compressed image

I have an wavelet compressed image, but not sure what parameter its using for compression, is there a way to un-compress this image?. 我有一个小波压缩的图像,但不确定用于压缩的参数是什么,有没有办法解压缩该图像? I tried using a jpeg-2000 image viewer but it did not help. 我尝试使用jpeg-2000图像查看器,但没有帮助。 As per my understanding one should know the wavelet on which it was compressed to proceed further, but this information is missing at present. 根据我的理解,应该知道将其压缩以进一步进行处理的小波,但是目前缺少此信息。 Does this mean the images remain encrypted and cant be decoded? 这是否意味着图像仍保持加密且无法解码?

Do you know the data format? 你知道数据格式吗? if you plot it can you see the main bands and sub bands at the various levels of detail? 如果绘制它,可以看到各个细节级别的主要波段和子波段吗?

Once you have the data format, you can simply try a few possible wavelet shapes, starting with the Haar for simplicity. 一旦有了数据格式,就可以简单地尝试几种可能的小波形状,为简单起见,从Haar开始。 At least you will get a good impression of the image content. 至少您会对图像内容有良好的印象。

If you don't know the data format, you are probably stuffed. 如果您不知道数据格式,则可能已经塞满了。
