prepare my own data set and creat LMDB format data set

[zofnat bar]

Hello,

I'm new to Caffe and I'm willing to know how to prepare my own data set:  (i want to creat LMDB format data set)

I'm understand that i need to prepare:

1 folder train: the inside of the training picture  --- > in this folder i put my pictures to train- jpg file?

2 Folder Val: which put the picture of Val --- > but whats is mean picture of val ? 

3 train.txt: the file name of the training picture and the corresponding category  ----> where i put this file? and how is look like?

4 val.txt: test images of the file name and the corresponding category --- > where i put this file? and how is look like?

 

in yellow is the questions.

Thanks :)

hi again , thanks a lot.
now after i training my data set , the model based on about 239 images which is divided in to 3 categories (labels).
when i try to classify image i have shape mismatch.

I run this:
~/Documents/caffe$ ./build/examples/cpp_

classification/classification.bin   models/bvlc_reference_caffenet/deploy.prototxt   models/bvlc_reference_caffenet/bvlc_reference_caffenet.caffemodel   data/ilsvrc12/imagenet_mean.binaryproto   data/ilsvrc12/synset_words.txt   examples/images/cat.jpg
