Multi-regime analysis for computer vision-based traffic surveillance using a change-point detection algorithm

no code implementations7 Nov 2020 Seungyun Jeong, Keemin Sohn

An autoencoder was used to reduce the dimensions of input images, and reduced feature vectors were used to implement the online change-point algorithm.

Non-anchor-based vehicle detection for traffic surveillance using bounding ellipses

no code implementations5 Oct 2020 Byeonghyeop Yu, Johyun Shin, Gyeongjun Kim, Seungbin Roh, Keemin Sohn

As a result, the performance of the two models with bounding ellipses exceeded that of the reference models with bounding boxes.

Data Augmentation
