Preparing Data for CifarNet from text file

[sharath s]

Hello

I have a text file with two classes, i have arranged them in text file as

Pic1.JPEG 0
Pic2.JPEG 0
Pic3.JPEG 1
Pic4.JPEG 1

I wanted to convert this text file to lmdb format so that i can use the lmdb format in the cifarnet.

I know from the Imagenet example using the script ./convert_imagenet.sh, i can convert the txt file to lmdb format.

Can i convert the text file to lmdb format using the scirpt in the imagenet example and use the converted lmdb format in the cifarnet?


Do you think it works? is there any other way i can convert text(with format above)  to the lmdb format required by cifarnet?


Thanks

I successfully converted the text files to lmdb format and it used the converted format with the CIFARNET.

What i did was, initially i created text files as mentioned below and i used the script which came along with imagenet example - ./create_imagenet.sh to convert text files to lmdb. (by changing the paths accordingly). i also used ./make_imagenet_mean.sh to produce mean.binaryproto. 

These two files are enough to train CifarNet with your own dataset. 

hope this is helpful, if someone faces same situtation.

In general, you  can use the convert_imageset and compute_image_mean executables that are in the tools/ directory, to convert to lmdb/leveldb and to compute the mean image.

The imagenet scripts you mention are just the above modified for imagenet.
