Estimation of leaf area by mobile application: Fast and accurate method

Leaf area estimation by a simple and non-destructive method

In this study, the relation between leaf area and its dimensions was estimated using a non-destructive method. This method is based on this fact that the leaf shape does not change during the growing season. In this method, leaf area during the growing season is estimated based on the dimensions of the smallest leaf in the initial stage of plant growth or at any growth stage by measuring the le...

Adaptive search area for fast motion estimation

In this paper a new method for determining the search area for motion estimation algorithm based on block matching is suggested. In the proposed method the search area is adaptively found for each block of a frame. This search area is similar to that of the full search (FS) algorithm but smaller for most blocks of a frame. Therefore, the proposed algorithm is analogous to FS in terms of reg...

Rapid estimation of sunflower leaf area from linear measurements

Fast and Accurate Structure and Motion Estimation

This paper describes a system for structure-and-motion estimation for real-time navigation and obstacle avoidance. We demonstrate a technique to increase the efficiency of the 5-point solution to the relative pose problem. This is achieved by a novel sampling scheme, where we add a distance constraint on the sampled points inside the RANSAC loop, before calculating the 5-point solution. Our set...

Accurate Area Estimation by Data-Driven Decomposition of Mixed Pixels

There are many image processing applications where the area of an object has to be estimated as accurately as possible. A well-known example is the area estimation of agricultural elds, which is of great importance for the management of the agricultural subsidy system of the European Union. The area of an object can be estimated using both classiication, which allocates a pixel to a single clas...
