摘要:This note describes two operators that respond to step edges, but not to ramps. The first is similar to the digital Laplacian, but uses the max, rather than the sum, of the x and y second differences. The second uses the difference between the mean and median gray levels in a nei...

摘要:Hundreds of simple target-detection algorithms were tested on mid- and long-wave forward-looking infrared images. Each algorithm is briefly described. Indications are given as to which performed well. Most of these simple algorithms are loosely derived from standard tests of the ...

摘要:An automatic (or aided) target recognizer (ATR) consists of two essential stages: detection and recognition. This chapter covers detection algorithms for literal imagery and ground targets, which are the most basic cases. There are a large number of other cases that aren’t c...

摘要:The human brain has about 90 billion neurons, each with roughly one thousand synaptic connections to other neurons. However, it does not follow that if we build a computer with equivalent processing power and connectivity, it would match human functionality as an emergent pr...
