Imwrite bitdepth
Witryna1 lis 2013 · Thank you Douglas, but when I write the Mat (the resultant Mat) object using imwrite to a file as PNG file, the file properties show the 'bit depth' as '8' rather than '1'. Is there special way I need to use imwrite to accomplish this or some other technique exists. Thanks MB mahabudhi (Nov 1 '13) edit threshold, and then save as pbm, not png Witryna》》 image_bytes = K.Width * K.Height * K.BitDepth / 8; 》》 compressed_btyes = K.FileSize; 》》 compression_ratio = image_bytes / compressed_bytes 7. 数据类型。MATLAB的数据类型包括： 8. double 双精度浮点 9. uint8 无符号8位整数 10. uint16 无符号16位整数 11. uint32 无符号32位整数 12. int8 有符号8位整数
