How to convert CK+ dataset to .npy

[fitrialif]

Load data

X = np.load('CKP_X.npy')
Y = np.load('CKP_Y.npy')

Please take a look at these awesome scripts:

1. https://github.com/rolanvc/cs295-PA1/blob/master/preproc.py
2. https://github.com/rolanvc/cs295-PA1/blob/master/preproc2.py
3. https://github.com/rolanvc/cs295-PA1/blob/master/preproc3.py
4. https://github.com/rolanvc/dexpression/blob/master/utils.py

@fitrialif , Hope these helped. Please reopen if you have any queries.

hi @arundasan91 ,
Thank you for the code.
I have ran this code until preproc3.py and the resize image was produce but when I try run utils.py code nothing happen. Still cannot convert to numpy format.

Hey @fitrialif , Maybe you're missing something. What you'd want to do is to understand what the function filestoTFdata https://github.com/rolanvc/dexpression/blob/master/utils.py#L4-L33 is doing. You've to call that function with a list of filenames (absolute paths). The function is well documented. Let me know how it goes.

Thanks,
Arun

Hi... it's this how to run this code python utils.py /home/fitrialif/resize I try run like this but there is no numpy output

@fitrialif ,

What you are doing is to run the utils.py file with an argument /home/fitrialif/resize. This won't work as:

1. The function is not expecting any arguments.
2. The function needs a list of filenames (absolute path).

Also, Line 33 should ring some bells. The function is returning the concatenated array.

If you'd want to save the arrays, add a line after Line 38 to save the variables images and labels to disk. You can use numpy.save to do that.

What you need to do is to create a list of filenames say:

filelist = ['/home/fitrialif/resize/001.jpg', '/home/fitrialif/resize/002.jpg', '/home/fitrialif/resize/003.jpg']

You can use os.listdir or something similar for that. Maybe replace the filelist in Line 37 with the one you create.

Finally, run the code using python utils.py

this is my code import tensorflow as tf import os import numpy as np import cv2 def filestoTFdata(files): ''' :param files:is a list of filenames of format E$_xxxxxxx.png representing images of emotions. The $ is a number from 1..7 representing the emotion (anger, contempt, disgust, fear, happy, sadness, surprise) :return: a list of (image) data, and a list of one-hot-arrays representing emotion labels ''' images= [] labels = [] for f in files: # get the filename. extract the E$ to acquire emotion label fn = os.path.basename(f) emo = int(fn.split('_')[0][1]) - 1 #create a one-hot vector onehot = np.array([int(i==emo) for i in range(7)], dtype=np.uint8) #reshape to be as expected i.e. (1,7) emo_label = np.reshape(onehot, (1, 7)) # add to list labels.append(emo_label) # read the imagee as grayscale img = cv2.imread(f, cv2.IMREAD_GRAYSCALE) # expand to that expected expanded_img = np.expand_dims(np.expand_dims(img,0),3) # convert to numpy array image = np.array(expanded_img) # add to list images.append(image) np.save('x.npy',images) np.save('Y_.npy',labels) # return lists of images and labels return images, labels # test the function above if __name__== "__main__": filelist = ['/home/fitrialif/PHDFitri/codeFER/preprocess_ck+/resize/'] images, labels = filestoTFdata(filelist) i run using python utils.py but i get this error Traceback (most recent call last): File "utils.py", line 41, in <module> images, labels = filestoTFdata(filelist) File "utils.py", line 18, in filestoTFdata emo = int(fn.split('_')[0][1]) - 1 IndexError: string index out of range

@fitrialif , I strongly suggest you brush up your Python skills and understand the context in which the code is running. Please refer my previous comment for filelist; it should be a list. If you've a friend who can lend a hand who knows Python, please meet with him/her and discuss this together.

Thanks,
Arun

@fitrialif have you completed this task. I am facing the same problem can you help me??

The links to the files are dead. Can I assume that all 5876 are loaded and resized to 224x224x1 for inputting into the network?

[GaroBozadjian]

The links that you uploaded is not working, can you update them so we can use the CKP dataset please

[edgalsanchez]

The links are dead, can you update them? Please

[arundasan91]

@edgalsanchez , sorry. I checked for the repo, seems it was removed.

[arundasan91]

There are many projects which uses CK+ dataset. Unfortunately, since I have used my code in a private project, I cannot share it now. Please search for CK+ dataset in github.
