Image Tool Box

This is a python module to help us to do the tranformations between raw file, csv file, and numpy array.

Requirements

It would be better if you got those version number bigger than these below

• python >= 3.9
• numpy >= 1.22
• pandas >= 1.4
• matplotlib >= 3.4.3

you can download those module for the latest version with the command below

handsomeguy@supercomputer:~$ pip install ImgToolBox
handsomeguy@supercomputer:~$ pip install numpy
handsomeguy@supercomputer:~$ pip install pandas
handsomeguy@supercomputer:~$ pip install matplotlib

Usage example

your structure could probably look like this below

.
+-- yourpythonfile.py
|
+--src/
   +--catimage.raw
   +--dogimage.csv
|
+--output/
|

# @yourpythonfile.py

import ImgToolBox.ImgFile as ITB

# you should put the path of raw file in the raw2arr fumction and you will get the numpy array from raw file
array = ITB.toArray('src/catimage.raw', (300, 800), dtype = '>u2')

# you can get the numpy array from the path of csv file
new_array = ITB.toArray('src/dogimage.csv')

# aftere doing this, you could get the csv file in the path you want
ITB.arr2csv(new_array, 'output/dogimage.csv')

# you can create a frame difference image by doing this
arr1 = np.array([50, 50, 50]).astype(np.uint8)
arr2 = np.array([10, 40, 90]).astype(np.uint8)
arr3 = ITB.imageDiff(arr1, arr2, 10)
# arr3 = [255   0 255]

# you can easily transform image array to histogram
ITB.saveHist(array, 'myHistogram.png', bins = 1024, title = "arr", xlim=(0, 1024), ylim=(0, 10000))
