국부통계처리에 근거한 금석문영상의 적응영상향상 기법을 제안한다. 영상의 국부통계처리 값들을 영상향상을 위한 적응실현으로 활용하여 평활화와 상세화의 경로를 조정한다. 미세부분에서는 영상이 향상되고 평활영역에서는 잡음이 억제된다 금석 문영상의 모델링을 위해 한지밀착본(韓紙密着本)디지털영상(HSDI, Hanzi squeezed digital image)의 전처리 과정을 수행하였다. HSDI 분석을 통해 국부통계처리 값들을 산출하고 영상을 모델링한다. 본 기법을 HSDI에 적용하여 에지부분의 미세한 변화를 향상시키고 배경영역을...

시그마필터는 특성화된 근접분포구도로 시그마 값을 국부통계값들로부터 산출한다. 표준평균필터를 교정하여 잡음을 제거하는 동시에 에지를 보존하도록 설계되어 있으나 미세부분 향상에는 취약하다. 종래의 시그마 접근들도 잡음제거에 치중되어 있었을 뿐 특징구역의 향상은 소홀하였다. 본 논문은 국부통계값들과 함수 부합을 활용한 적응영상향상 알고리즘을 제안한다, 이들 값들은 영상향상의 적응 실현에 유용하여 잡음을 평활시키고 영상의 미세부분을 향상한다. 국부적응처리를 위하여 매 이동창에서 평가척도를 만족하는...

The present study aimed at analyzing the genetic variability of indigenous goat breeds (Capra hircus) using the MHC-associated microsatellite markers BF1, BM1818, BM1258, DYMS1, and SMHCC1. The following breeds were included: Chinese Xuhuai, Indian Changthangi and Pashmina, Kenyan Small East African (SEA) and Galla, and Albanian Vendi. To examine genetic variability, the levels of heterozigosity, degrees of inbreeding, and genetic differences among the breeds were analyzed. The mean number of...

Echinacea (E.) purpurea herb is commonly known as the purple coneflower, red sunflower and rudbeckia. In this paper, we report the curative efficacy of an Echinacea extract in ■-irradiated mice. E. purpurea was given to male mice that were divided into five groups (control, treated, irradiated, treated before irradiation & treated after irradiation) at a dose of 30 mg/kg body weight for 2 weeks before and after irradiation with 3 Gy of ■-rays. The results reflected the detrimental...

Puerariae flos (PF) is a traditional oriental medicinal plant and has clinically been prescribed for a long time. The purpose of the present study was to examine the effect of PF on repeated stress-induced alterations of learning and memory on a Morris water maze (MWM) test in ovariectomized (OVX) female rats. The changes in the reactivity of the cholinergic system were assessed by measuring the immunoreactive neurons of choline acetyltransferase (ChAT) in the hippocampus after behavioral...

Xanthomonas campestris pv. campestris (Xcc) is the causal agent of black rot for cruciferous vegetables worldwide, especially for the cole crops such as cabbage and cauliflower. Due to the lack of resistant cabbage cultivars, black rot has brought about considerable yield losses in recent years in China. Understanding of the pathogen features is a key step for disease prevention, however, the pathogen diversity, population structure, and virulence are largely unknown. In this study, we studied...

The objective of this research was introduction of chit42 to tuber mustard plants through Agrobacterium- mediated transformation against white mold caused by Sclerotinia sclerotiorum. The binary plasmid pGisPEC1 was used in this study. Polymerase chain reaction analysis detected the transgene in 27 transformants with a transformation efficiency of 6.9%. Southern blot test was used to assess the copy number of transgene in tuber mustard plants. One, two, two, and two chit42- related bands were...

The incidence and distribution of Tobacco mosaic virus (TMV) and related tobamoviruses was determined using an enzyme-linked immunosorbent assay on 1,926 symptomatic horticultural crops and 107 asymptomatic weed samples collected from 78 highly infected fields in the major horticultural crop-producing areas in 17 provinces throughout Iran. The results were confirmed by host range studies and reverse transcription-polymerase chain reaction. The overall incidence of infection by these viruses in...
