Submissions are evaluated on the root mean squared error between the pixel intensities of the cleaned images and the pixel intensities of the original images, where both sets of images have been grayscaled.

# Submission File
Form the submission file by grayscaling your cleaned images, assigning each image an ID number, and producing a row per pixel in each image, in the following format:

```
1_1_2,0
```

corresponding to the following data:
1. which picture the data belongs to (filename)
2. the pixel's row image
3. the pixel's column
4. the intensity of the pixel (0, black, to 1, white).


The file should contain a header and have the following format:
```
id,value
1_1_1,1
1_2_1,1
1_3_1,1
```
etc.

A sample submission file is provided in the competition data.
