Main function:

Command: matlab /code/FigSplit.m

Inputs:

Image_file_path: The path to the image that needs separation.

Outputs:
The identified panels (in jpg format) from the compound image and their coordinates (in text format) at the original image.

Explainations of submodules called by FigSplit.m
Submodule 1: Image preprocessing (Lines 8-31 in FigSplit.m) Inputs:
Im_original: The original image that needs separation.
Outputs: Im0: The preprocessed image.

Submodule 2: Connected component analysis (/code/white_margin_detection.m)
Inputs:
Im0: The preprocessed image.
Outputs:
pointsforseparation: The coordinates of identified panels by using the connected component analysis method.

Submodule 3: Separation quality assessment (/code/evaluation.m)
Inputs:
Im0: The preprocessed image.
pointsforseparation: The coordinates of identified panels.
Outputs:
The coordinates of identified panels after the evaluation and self-correction process.

Submodule 4: Handle stitched image (/code/get_white_seg_recursion_function.m)
Inputs:
Im0: The preprocessed image.
Outputs:
The coordinates of identified panels by choosing the peak position of the horizontal projection or vertical projection.

Submodule 5: Handle blurry and fragmented image (/code/CCAuseSuan1.m)
Inputs:
Susan_im: The image generated by applying SUSAN edge detector to the preprocessed image im0.
Outputs:
The coordinates of identified panels by applying CCA method to Susan_im.

\subsection{Datasets}
