This came out form my MS’s thesis, and lead to ICPR workshop and Pattern Recognition Letters Journal publications. For example, semantic segmentation helps SDCs (Self Driving Cars) discover the driveable areas on an image. It is used to recognize a collection of pixels that form distinct categories. We use cookies to optimize site functionality, personalize content and ads, and give you the best possible experience. From the GIF above, we can see that we have two classes in the semantic segmentation process ( road and not road ) which are colored accordingly. In this project, we'll label the pixels of the free space on a road in images using a Fully Convolutional Network (FCN).
