How to enter multiple slice points to get three output layers

[Oier Mees]

Hi,

I have rgb images  consisting of three concatenated images and would like to use the slice layer to separate them. As slice_point is an int vector, there is apparently a way of specifying multiple slicing points, but I don't know the syntax. I have following definition, which doesn't work.

layers {

    name: "slice_frames"

    type: SLICE

    bottom: "data"

    top: "data_left"

    top: "data_middle"

    top: "data_right"

    slice_param {

        slice_dim: 1

        slice_point: 3,6

    }

}

Does anyone know how to specify two slice points (3 and 6) so I get three output layers? Or is slice layer constrained to two tops and I  have to use two consecutive slice layers to get three output layers?

Cheers,

Oier

slice_point is a repeated field, just repeat it as many times as needed, and provide enough tops.

layers {

    name: "slice_frames"

    type: SLICE

    bottom: "data"

    top: "data_left"

    top: "data_middle"

    top: "data_right"

    slice_param {

        slice_dim: 1

        slice_point: 3

        slice_point: 6

    }

}

Hi Oier,

   How did you add three Images onto LMDB?

   If I'm not wrong u have 3 Images and One label right?

I just wrote a method to read the corresponding image and add them in a datum.

Hi!
I'm trying to do the same you did.
Can you explain me how did you do this method? I looked into convert_imageset but I don't understand enough about it to know what to change.
