Flies see second-order motion
Motion detection is nearly ubiquitous among visual animals. Simple ‘first-order’ motion in an image is defined by spatiotemporal correlations in luminance, and is useful for tasks such as identifying a bright butterfly crawling on a tree. Humans additionally perceive ‘second-order’ motion [1], defined by spatiotemporal correlations in higher-order image statistics, such as local contrast or tex...
متن کاملDeterministic second-order patterns
Second-order patterns, together with second-order matching, enable concise specification of program transformation, and have been implemented in several program transformation systems. However, second-order matching in general is nondeterministic, and the matching algorithm is so expensive that the matching is NP-complete. It is orthodox to impose constraints on the form of higher-order pattern...
متن کاملFast Second Order Learning
The paper presents the eecient training program of multilayer feedforward neu-ral networks. It is based on the best second order optimization algorithms including variable metric and conjugate gradient as well as application of directional minimization in each step. Its eeciency is proved on the standard tests, including parity, dichotomy, logistic and 2-spiral problems. The application of the ...
متن کاملWhat does second-order vision see in an image?
The human visual system is sensitive to both first-order variations in luminance and second-order variations in local contrast and texture. Although there is some debate about the nature of second-order vision and its relationship to first-order processing, there is now a body of results showing that they are processed separately. However, the amount, and nature, of second-order structure prese...
متن کاملRegular Patterns in Second-Order Unification
The second-order unification problem is undecidable. While unification procedures, like Huet’s pre-unification, terminate with success on unifiable problems, they might not terminate on non-unifiable ones. There are several decidability results for infinitary unification, such as for monadic second-order problems. These results are based on the regular structure of the solutions of these proble...
