Invariant-Theoretic Methods in Scene Analysis and Structural Mechanics

Spectral and Spatial Invariant Image Retrieval using Scene Structural Matrix

We introduce Scene Structural Matrix (SSM), a novel image content descriptor and its application to invariant image retrieval. The SSM captures the overall structural characteristics of the scene by indexing the geometric features of the image. We employ a binary image tree (bintree) to partition the image and from which we derive multiscale geometric structural descriptors of the image. We hav...

2.080 Structural Mechanics Energy Methods in Elasticity

We seldom measure H from the center of earth. Therefore what we can easily measure is the change of the potential energy ∆W = (mg)(H −Ho) (8.2) The energy is always positive. It can e zero but it cannot be negative. The gravity force F = mg is directed towards the center of earth. Therefore there is a need for the negative sign in Eq. (8.2)). In the coordinate system of Fig. (8.1), the gravity ...

the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...

Scene Invariant Crowd Counting and Crowd Occupancy Analysis

In public places, crowd size may be an indicator of congestion, delay, instability, or of abnormal events, such as a fight, riot or emergency. Crowd related information can also provide important business intelligence such as the distribution of people throughout spaces, throughput rates, and local densities. A major drawback of many crowd counting approaches is their reliance on large numbers ...
