Caffe: Network with 2 images input.

[filipetrocadoferreira]

Which is the simplest way to implement a network with 2 images as inputs?

Just use two ImageData layers. After that you can concatenate it if you need.

Do you have an example prototxt?

[filipetrocadoferreira]

I've used an RGB representation (and use of discard data layer)

[brothertook]

layer {
name: "weekly-data"
type: "ImageData"
top: "data_img0"
top: "vid"
image_data_param {
source: "train.txt"
is_color: true
batch_size: 15
}
transform_param {
scale: 0.0039215684

}

}

layer {
name: "weekly-data1"
type: "ImageData"
top: "data_img1"
top: "vid1"
image_data_param {
source: "test.txt"
is_color: true
batch_size: 15
}
transform_param {
scale: 0.0039215684

}

}

layer {
name: "concat"
bottom: "data_img0"
bottom: "data_img1"
top: "data_img"
type: "Concat"
concat_param {
axis: 1
}
}

And in inference how do you copy your data to each one of input layers(c++)

[brothertook]

source: "train.txt"
train.txt contains a list if image file name one per line.
caffe get files for that list and make blob . So I don'n have to write any c++ code to load data.

Use the caffe-users list instead. This helps developers maintain a clear, uncluttered, and efficient view of the state of Caffe.

how about the labels in the softmax layer? there are 2 sources of labels after the concat.. how to handle this?
