Nonlinear pattern recognition correlators based on color-encoding single-channel systems.
2004
In color pattern recognition, color channels are normally processed separately and afterward the correlation outputs are combined. This is the definition of multichannel processing. We combine a single-channel method with nonlinear filtering based on nonlinear correlations. These nonlinear correlations yield better discrimination than common matched filtering. The method codes color information as amplitude and phase distributions and is followed by correlations related to binary decompositions. The technique is based on binary decompositions of the red, green, and blue and the hue, saturation, and intensity monochromatic channels of the reference and of the input scene, after which the bin…
Artificial intelligence for affective computing : an emotion recognition case study.
2020
This chapter provides an introduction on the benefits of artificial intelligence (Al) techniques for the field of affective computing, through a case study about emotion recognition via brain (electroencephalography EEG) signals. Readers are first pro-vided with a general description of the field, followed by the main models of human affect, with special emphasis to Russell's circumplex model and the pleasur-arousal-dominance (PAD) model. Finally, an AI-based method for the detection of affect elicited via multimedia stimuli is presented. The method combines both connectivity-and channel-based EEG features with a selection method that considerably reduces the dimensionality of the data and …
Charipinae (Hymenoptera: Cynipoidea: Figitidae) from Mexico with Description of Three New Species
2013
Abstract Charipinae collected in different regions of Mexico have been studied. Twelve species are cited for the first time: Alloxysta arcuata (Kieffer, 1902), Alloxysta brevis (Thomson, 1862), Alloxysta castanea (Hartig, 1841), Alloxysta fuscicornis (Hartig, 1841), Alloxysta mullensis (Cameron, 1883) ; Alloxysta victrix (Westwood, 1833 ); Phaenoglyphis americanaBaker, 1896; Phaenoglyphis calvertiAndrews, 1978; Phaenoglyphis falcataAndrews, 1978; Phaenoglyphis stenosAndrews, 1978; Phaenoglyphis stricta (Thomson, 1877); and Phaenoglyphis villosa (Hartig, 1841).

Revision of the types of species of Alloxysta described by Cameron and Fergusson (Hymenoptera: Figitidae: Charipinae) and deposited in the Natural Hi…
2013
Type material of the species of Alloxysta described by Cameron and Fergusson and deposited in the Natural History Museum of London has been revised. Seven species are considered valid: Alloxysta abdera Fergusson, 1986, A. basimacula (Cameron, 1886), A. crassa (Cameron, 1889), A. mullensis (Cameron, 1883), A. piceomaculata (Cameron, 1883), A. pleuralis (Cameron, 1879) and A. semiaperta Fergusson, 1986. A. basimacula, A. crassa, A. maculicollis (Cameron, 1886), A. perplexa (Cameron, 1889) and A. piceomaculata are here removed from synonymy with A. macrophadna (Hartig,1841). A. ruficeps (Cameron, 1883) is removed from synonymy with A. victrix (Westwood, 1833). A. caledonica (Cameron, 1886) and…
Revision of V.I. Belizin’s type material of Alloxysta (Hymenoptera: Figitidae: Charipinae) deposited in the Zoological Institute of the Russian Acade…
2012
A revision of the type material of species of the genus Alloxysta described by V.I. Belizin deposited in the Zoological Institute of the Russian Academy of Sciences is provided. Six Alloxysta species were studied, three of which are valid: A. aurata Belizin, 1968, A. proxima Belizin, 1962, and A. salicicola Belizin, 1973. Valid species are completely re-described and their diagnostic characters are illustrated. Three remaining species are synonymised with other species of this genus: Alloxysta brevicella Belizin, 1966 with A. citripes (Thomson, 1862), A. capillata Belizin, 1962 with A. castanea (Hartig, 1841), and A. contineus (Belizin, 1962) with A. victrix (Westwood, 1833). The characters…
Keys to world Charipinae (Hymenoptera, Cynipoidea, Figitidae)

Eight genera of Charipinae are defined, keyed out, and illustrated. Keys for all charipine species within each valid genus, includingAlloxysta,Apocharips,Dilyta,Phaenoglyphis, andThoreauana, are presented, except forDilapothor,Lobopterocharips, andLytoxysta, which are monotypic. Figures are provided to show the diagnostic morphological features as used in the keys.
Revision of the Holarctic species of Dilyta Förster (Hymenoptera: Figitidae: Charipinae) with descriptions of four new species from the eastern Palae…
2011
The genus Dilyta, and the known species of this genus present in the Holarctic, D. subclavata Forster from Europe and D. rathmanae Menke and Evenhuis from USA, are redescribed. Four new species of Dilyta are described from the eastern Palaearctic region: D. aleevae sp. n. from Kazakhstan, D. japonica sp. n. from Japan, and D. longinqua sp. n. and D. sinica sp. n. from China. All six species have an ∩ -shaped carina on the apex of the scutellum; this character differentiates these species from the Afrotropical species, which instead have two small symmetrical and parallel carinae. A key to the species of Dilyta in the Holarctic is provided. Apocharips talitzkii (Belizin) is synonymyzed with …
