Considering the population growth rate of recent years, a doubling of the current worldwide
crop productivity is expected to be needed by 2050. Pests and diseases are a major …

We present an overview of various edge and line oriented approaches to contour detection
that have been proposed in the last two decades. By edge and line oriented we mean …

This paper presents a database containing'ground truth'segmentations produced by humans
for images of a wide variety of natural scenes. We define an error measure which quantifies …

Now in its fifth edition, John C. Russ's monumental image processing reference is an even
more complete, modern, and hands-on tool than ever before. The Image Processing …

Images containing faces are essential to intelligent vision-based human-computer
interaction, and research efforts in face processing include face recognition, face tracking …

Edges characterize boundaries and are therefore a problem of fundamental importance in
image processing. Image Edge detection significantly reduces the amount of data and filters …

Many different low-level feature detectors exist and it is widely agreed that the evaluation of
detectors is important. In this paper we introduce two evaluation criteria for interest points' …

The Canny edge detector is widely used in computer vision to locate sharp intensity
changes and to find object boundaries in an image. The Canny edge detector classifies a …

The investment in an automated fabric defect detection system is more than economical
when reduction in labor cost and associated benefits are considered. The development of a …

To master the fundamentals of image registration, there is no more comprehensive source
than 2-D and 3-D Image Registration. In addition to delving into the relevant theories of …
