Scale Invariant Optical Flow

چکیده
Scale variation commonly arises in images/videos, which cannot be naturally dealt with by optical flow. Invariant feature matching, on the contrary, provides sparse matching and could fail for regions without conspicuous structures. We aim to establish dense correspondence between frames containing objects in different scales and contribute a new framework taking pixel-wise scales into consideration in optical flow estimation. We propose an effective numerical scheme, which iteratively optimizes discrete scale variables and continuous flow ones. This scheme notably expands the practicality of optical flow in natural scenes containing various types of object motion.

متن کاملMulti-Resolution Estimation of Optical Flow for Vehicle Tracking
This paper presents a hierarchical multi-resolution estimation of optical flow for a vehicle tracking system which can be used in a practical environment. Aiming at accurate estimation of optical flow, we construct a strong feature tracking system based on the Shi-Tomasi approach. As a feature detector, we use a Scale-Invariant Feature Transform (SIFT) algorithm, which not only firmly focuses o...
متن کاملDense Descriptors for Optical Flow Estimation: A Comparative Study
Estimating the displacements of intensity patterns between sequential frames is a very well-studied problem, which is usually referred to as optical flow estimation. The first assumption among many of the methods in the field is the brightness constancy during movements of pixels between frames. This assumption is proven to be not true in general, and therefore, the use of photometric invariant...
متن کاملVision Based Mapless Navigation System for Mobile Robots Using Scale Invariant Features and Optical Flow
Autonomous robots operating in an unknown and uncertain environment must be able to cope with dynamic changes to that environment. For a mobile robot to navigate successfully to a goal whilst avoiding obstacles is a challenging problem. The mapless navigation technique resembles human behaviours more than other approaches This paper presents a new mapless navigation strategy, based on a multi-s...
