Not allowing images small than certain dimensions

I have a model that saves user profile images. If the image that is uploaded is greater than 200x200 pixels, then we resize to 200x200. If the image is right at 200x200, then we return that image. What I want now is to throw an error to the user saying that this image is too small and is not allowed. Here's what I have:

class Profile(models.Model):
    GENDER_CHOICES = (
        ('M', 'Male'),
        ('F', 'Female'),
    )
    user    = models.OneToOneField(User, null=True, on_delete=models.CASCADE)
    bio     = models.CharField(max_length=200, null=True)
    avatar  = models.ImageField(upload_to="img/path")
    gender  = models.CharField(max_length=1, choices=GENDER_CHOICES, null=True)
def save(self, *args, **kwargs):
    super(Profile, self).save(*args, **kwargs)
    if self.avatar:
        image = Image.open(self.avatar)
        height, width = image.size
        if height == 200 and width == 200:
            image.close()
            return

        if height < 200 or width < 200:
            return ValidationError("Image size must be greater than 200")
        image = image.resize((200, 200), Image.ANTIALIAS)
        image.save(self.avatar.path)
        image.close()

When an image is smaller than 200px in width or height, the image should not be uploaded. However, the image is being uploaded. How can I stop this from happening?

Instead of doing that in save() method, you can do it in forms:

from django.core.files.images import get_image_dimensions
from django import forms

class ProfileForm(forms.ModelForm):
   class Meta:
       model = Profile

   def clean_avatar(self):
       picture = self.cleaned_data.get("avatar")
       if not picture:
           raise forms.ValidationError("No image!")
       else:
           w, h = get_image_dimensions(picture)
           if w < 200:
               raise forms.ValidationError("The image is %i pixel wide. It's supposed to be more than 200px" % w)
           if h < 200:
               raise forms.ValidationError("The image is %i pixel high. It's supposed to be 200px" % h)
       return picture

Reason for this is because, when you have called save(), image is already uploaded. So its better to do it in forms.

Preprocessing your images for machine learning (image recognition)

During my studies at JKU there was a task for preprocessing images for a machine learning project. It is necessary to clean the raw images before using them in a learning algorithm, so thats why we create a pre-processing function. I think it can be quite useful for others as well so I want to share a bit of my approach. The file is structured in a way that it is easy to understand and also should have a tutorial-like effect.
