Still, those practical advantages make it extremely easy to deploy for a wide variety of images, enabling rapid experimentation. The downside is that the model loses some generality, perhaps overfitting to the training samples, and thus can feel a bit repetitive or patchy. This provides a way to do it quickly and cheaply.Īnother important quality of pix2pix is that it requires a relatively small number of examples – for a low-complexity task, perhaps only 100-200 samples, and usually less than 1000, in contrast to networks which often requires tens or even hundreds of thousands of samples. This can be very useful as well suppose you are in charge of a startup which is generating special types of label maps from satellite images. Of course, we could have trained the network in the other direction as well train it to generate the label maps from the real images. This leads us to believe that we can mock up whole new label maps and create realistic looking facades from them! This could be very useful for an architect they can sketch a design for a building and then quickly prototype textures for it (perhaps choosing from several dozen since they are so easy to produce). But it gets most of the main architectural features in the right place. The output has numerous features that are different from the target, and has a somewhat different color, and is especially guessing in the regions where the labels are sparse. Let’s look at a small sample of images from the facades dataset.

We get a good sense of this by considering a more complicated example, that of the CMP facades dataset which pix2pix has a download link for. This makes pix2pix highly flexible and adaptable to a wide variety of situations, including ones where it is not easy to verbally or explicitly define the task we want to model. It makes no assumptions about the relationship and instead learns the objective during training, by comparing the defined inputs and outputs during training, and inferring the objective. The nice thing about pix2pix is that it is generic it does not require pre-defining the relationship between the two types of images. Deblurring or denoising images can be framed in this way, and indeed there had been a great deal of past research in learning various specific image-to-image translation tasks like those and others. Many important image processing tasks can be framed as image to image translation tasks of this sort.

We should expect that it will be able to color new, previously unseen black & white images to around the same accuracy. Output from colorizing black & white (made with colorize-it)Īs we see above, the output is not identical to the input, but the network does a fairly decent job.
