20161114---手写图片转为lmdb

1.PS制图片；

2.将create_imagenet.sh复制到myself下并重命名为create_lmdb.sh；

  3.将数据集的train.txt和val.txt(或者是test.txt)拷贝到myself下







4.修改create_lmdb.sh

 #!/usr/bin/env sh

# Create the imagenet lmdb inputs

# N.B. set the path to the imagenet train + val data dirs

set -e
EXAMPLE=examples/imagenet/myself

DATA=examples/imagenet/myself

TOOLS=build/tools
TRAIN_DATA_ROOT=examples/imagenet/myself/

VAL_DATA_ROOT=examples/imagenet/myself/
# Set RESIZE=true to resize the images to 256x256. Leave as false if images have

# already been resized using another tool.

RESIZE=false

if $RESIZE; then

  RESIZE_HEIGHT=28

  RESIZE_WIDTH=28

else

  RESIZE_HEIGHT=0

  RESIZE_WIDTH=0

fi
if [ ! -d "$TRAIN_DATA_ROOT" ]; then

  echo "Error: TRAIN_DATA_ROOT is not a path to a directory: $TRAIN_DATA_ROOT"

  echo "Set the TRAIN_DATA_ROOT variable in create_imagenet.sh to the path" \

       "where the ImageNet training data is stored."

  exit 1

fi
if [ ! -d "$VAL_DATA_ROOT" ]; then

  echo "Error: VAL_DATA_ROOT is not a path to a directory: $VAL_DATA_ROOT"

  echo "Set the VAL_DATA_ROOT variable in create_imagenet.sh to the path" \

       "where the ImageNet validation data is stored."

  exit 1

fi
echo "Creating train lmdb..."
GLOG_logtostderr=1 $TOOLS/convert_imageset \

    --resize_height=$RESIZE_HEIGHT \

    --resize_width=$RESIZE_WIDTH \

    --shuffle \

    $TRAIN_DATA_ROOT \

    $DATA/train.txt \

    $EXAMPLE/myself_train_lmdb
echo "Creating val lmdb..."
GLOG_logtostderr=1 $TOOLS/convert_imageset \

    --resize_height=$RESIZE_HEIGHT \

    --resize_width=$RESIZE_WIDTH \

    --shuffle \

    $VAL_DATA_ROOT \

    $DATA/val.txt \

    $EXAMPLE/myself_test_lmdb
echo "Done."
