CNN for Grey Images

[benediktschifferer (Benedikt S)]

Hello WaterRocket8236,

there is already a thread about that topic:

Using vgg with greyscale images

I am in lesson 2 and trying to apply the finetune of the vgg model to other datasets. I have tried with the Statefarm driver competition and it works relatively well (0.92 val acc). But when I try with a dataset that has greyscale images (https://www.kaggle.com/c/datasciencebowl) I only reach 0.34 acc. Is there any preproccesing needed with a greyscale dataset?

I received the better results by using a DenseNet from scratch.

Bests,
Benedikt
