Unconstrained stereoscopic matching of lines
The computation of horizontal binocular disparities used in stereoscopic depth perception depends
upon the identification of corresponding features in the two retinal images. In principle, binocular
matching is a two-dimensional problem that considers matches in all possible meridians. Normally,
constraints such as end points or crossing points limit the direction and magnitude of matches. If
matching is unconstrained, such as is the case with long lines, it is completely ambiguous. Under these
conditions the default match will be determined by the operating range, or upper disparity limit, of
matchable vertical and horizontal disparities. We computed the operating range of vertical matches for
stereoscopic depth as a function of line orientation. Our results suggest that the two-dimensional
operating range is anisotropic for vertical and horizontal disparity and that unconstrained matches are
not based upon either epipolar geometry or nearest neighbor constraints, but rather the mean of
disparity estimates within the operating range for binocular matches. This operating range can be
extended vertically when matches are constrained by image primitives

Vampires in the village Žrnovo on the island of Korčula: following an archival document from the 18th century
Središnja tema rada usmjerena je na raščlambu spisa pohranjenog u Državnom arhivu u Mlecima (fond: Capi del Consiglio de’ Dieci: Lettere di Rettori e di altre cariche) koji se odnosi na događaj iz 1748. godine u korčulanskom selu Žrnovo, kada su mještani – vjerujući da su se pojavili vampiri – oskvrnuli nekoliko mjesnih grobova. U radu se podrobno iznose osnovni podaci iz spisa te rečeni događaj analizira u širem društvenom kontekstu i prate se lokalna vjerovanja.The main interest of this essay is the analysis of the document from the State Archive in Venice (file: Capi del Consiglio de’ Dieci: Lettere di Rettori e di altre cariche) which is connected with the episode from 1748 when the inhabitants of the village Žrnove on the island of Korčula in Croatia opened tombs on the local cemetery in the fear of the vampires treating.
