“…Their approach requires lower computation power and memory. Hernandez et al [23] proposed a combination of color-based and texture line detector approach to detect boundaries for unstructured roads. In the color-based detector, a white balance algorithm is utilized to reduce the impact of illuminations while the texture line detector combines the Canny edge detector with Hough transform to identify parallel boundaries of the road.…”

Road boundary estimation is an essential task for autonomous vehicles and intelligent driving assistants. It is considerably straightforward to attain the task when roads are marked properly with indicators. However, estimating road boundary reliably without prior knowledge of the road, such as road markings, is extremely difficult. This paper proposes a method to estimate road boundaries in different environments with deep learning-based semantic segmentation, and without any predefined road markings. The proposed method employed an encoder-decoder-based DeepLab architecture for segmentation with different types of backbone networks such as VGG16, VGG19, ResNet-50, and ResNet-101 while handling the class imbalance problem by weighing the loss contribution of the model's different outputs. The performance of the proposed method is verified using the 'ICCV09DATA' dataset. The method outperformed other existing methods and achieved the accuracy, precision, recall, f-measure of 0.9596±0.0097, 0.9453±0.0118, 0.9369±0.0149, and 0.9408±0.0135 respectively while using RestNet-101 as a backbone network and Dice Coefficient as a loss function. The detailed experimental analysis confirms the feasibility of the proposed method for road boundary estimation in different challenging environments.
