Read compressed or uncompressed NorPix image sequence in MATLAB.
This script can read all frames or a set reading window.
Index file will be used if available and named as the source file
(eg. test.seq.idx). Otherwise the script will skip through a compressed
sequence from the beginning (may take some time).
INPUTS
fileName: Char containing the full path to the sequence
frames: 1x2 double array of beginning and end frame
OUTPUTS
ImageCellArray: Cell array with images and timestamps of all allocated
frames.
headerInfo: Struct with header information (ImageWidth,
ImageHeight, ImageBitDepth, ImageBitDepthReal,
ImageSizeBytes, ImageFormat, AllocatedFrames,
Compression, HeaderVersion, HeaderSize, Description,
TrueImageSize, FrameRate).
EXAMPLES
Read all frames:
I = ReadJpegSEQ('C:\test.seq')
Read frames 2 to 13:
I = ReadJpegSEQ('C:\test.seq',[2 13])
Include sequence header information:
[I, headerInfo] = ReadJpegSEQ('C:\test.seq',[1 1])

Based on the work of Brett Shoelson (Norpix2MATLAB_MarksMod.m)
Thanks to NorPix support for providing sequence information.
This code was tested with Norpix SEQ
8-bit monochrome 75% lossy jpeg compression (24.07.2018)
8-bit monochrome uncompressed (03.06.2019)
8-bit(24) BGR 75% lossy jpeg compressed (04.10.2021)
Code for RGB included but not tested!
Please report any bugs and improvement suggestions!
