The Evolution of Modern Texture Processing
نویسنده
چکیده
This paper studies the evolution of image texture processing techniques over the last years Although texture is a fundamental attribute of images that has been shown to play an important role in human visual perception the quanti cation and characterization of texture is di cult Early texture processing techniques described texture deterministically or statistically in terms of repeated gray level patterns and the structure of the spatial placement of these patterns Gray level cooccurrence matrices were among the most successful such methods Modern texture processing techniques tend to characterize texture in terms of spatio spectrally localized coherent amplitude frequency and phase modulations This paper argues that evolution of the modern methods from the early methods can be directly linked to advances in the understand ing of mammalian biological visual function that occurred in the elds of psychophysics and physiology and furthermore that the most successful modern methods have evolved to emulate biological vision systems Evolution of modern texture processing methods is examined and several of the most successful new techniques such as the multidi mensional Teager Kaiser operator and AM FM modeling techniques are described in some detail The use of computed dominant modulations to perform e ective texture segmentation is demonstrated for the rst time This research was supported in part by the Army Research O ce under contract DAAH and by the Air Force O ce of Scienti c Research Air Force Systems Command USAF under grant number F Author preprint Submitted to Elektrik Turkish Journal of Electrical Engineering and Computer Sciences

The effect of twinning on texture evolution during ECAP processing of an AM30 magnesium alloy
An AM30 magnesium alloy was processed through ECAP method at 200 °C. Optical and transmission electron microscopy as well as electron back scattered diffraction (EBSD) technique were employed to characterize the deformed microstructure. A partially recrystallized microstructure including ultrafine/nano structures was obtained. The area fraction of 49% was measured for the recrystallized regions...
متن کاملTexture Evolution in Low Carbon Steel Fabricated by Multi-directional Forging of the Martensite Starting Structuree
It has been clarified that deformation and annealing of martensite starting structure can produce ultrafine-grained structure in low carbon steel. This study aims to investigate the texture evolution and mechanical properties of samples with martensite structure deformed by two different forging processes. The martensitic steel samples were forged by plane strain compression and multi-directio...
متن کاملEvolution of texture in an ultrafine and nano grained magnesium alloy
The evolution of texture was discussed during the formation of ultra-fine and nano grains in a magnesium alloy severely deformed through accumulative back extrusion (ABE). The microstructure and texture obtained after applying multiple deformation passes at temperatures of 100 and 250°C were characterized. The results showed that after single ABE pass at 100°C an ultrafine/nano grained microstr...
متن کاملEvolution of Texture and Grain Size during Equal Channel Angular Extrusion of Pure Copper and 6012 Aluminum
Among different SPD techniques, Equal channel Angular Pressing has attracted the most attentions, because of applying large strain to solid bulk materials. In this research, ECAP process up to 6 passes was carried out on a pure copper and a 6012 Al-Mg-Si alloy with BC route in ECAP dies with Φ=120 and Ψ=20 and diameter of 20and 10 millimeter respectively. Moreover, X-ray diffraction (XRD) syste...
متن کاملRecrystallization texture during ECAP processing of ultrafine/nano grained magnesium alloy
An ultrafine/nano grained AZ31 magnesium alloy was produced through four-pass ECAP processing. TEM microscopy indicated that recrystallized regions included nano grains of 75 nm. Pole figures showed that a fiber basal texture with two-pole peaks was developed after four passes, where a basal pole peak lies parallel to the extrusion direction (ED) and the other ~20° away from the transverse dire...
