WebDetails. Conditional random fields (CRFs) are a probabilistic framework for labeling and segmenting structured data, such as sequences. It can be put into the general framework of maximum likelihood. In PAL, L-BFGS algorithms is adopted for for maximizing the (penalized) likelihood function. WebAlso, the performance of four semantic segmentation approaches: Conditional Random Field (CRF), U-Net, Fully Convolutional Network (FCN) and DeepLabV3+ are analysed on ManipalUAVid dataset. It is seen that these algorithms perform competitively on UAV aerial video dataset and achieves an mIoU of 0.86, 0.86, 0.86 and 0.83 respectively.
