Using 11 microsatellite markers, we investigated the allelic variation and genetic structure of Cryptomeria japonica, across most of its natural distribution. The markers displayed high levels of polymorphism (average gene diversity=0.77, average number of alleles=24.0), in sharp contrast to the lower levels of polymorphism found in allozyme and cleaved(More)
We investigated 29 natural populations of Cryptomeria japonica using 148 cleaved amplified polymorphic sequence markers to elucidate their genetic structure and identify candidate adaptive genes of this species. In accordance with the inferred evolutionary history of the species during and after the last glacial episode, the genetic diversity was higher in(More)
A consensus map for sugi (Cryptomeria japonica) was constructed by integrating linkage data from two unrelated third-generation pedigrees, one derived from a full-sib cross and the other by self-pollination of F1 individuals. The progeny segregation data of the first pedigree were derived from cleaved amplified polymorphic sequences, microsatellites,(More)
In this paper, we propose a method for recognition of road markings from in-vehicle camera images. A road marking in in-vehicle camera images has a variety of appearance due to the change of position and distance between the camera and the road marking, blur effect, and so on. Therefore, accurate recognition of road markings becomes difficult in real(More)
Obtaining an accurate vehicle position is important for intelligent vehicles in supporting driver safety and comfort. This paper proposes an accurate ego-localization method by matching in-vehicle camera images to an aerial image. There are two major problems in performing an accurate matching: (1) image difference between the aerial image and the(More)
BACKGROUND We have previously reported that an increase of adenosine 3',5'-cyclic monophosphate (cAMP) in liver tissue after an administration of milrinone, a phosphodiesterase-3 inhibitor attenuates hepatic warm ischemia-reperfusion injury. The aim of this study was to determine whether cAMP-dependent protein kinase (protein kinase A) activation was(More)
Using appropriate training data is necessary to robustly recognize low-resolution characters by the subspace method. Former learning methods used characters actually captured by a camera, which required the collection of characters of all categories in various conditions. In this paper, we propose a new learning method that generates training data by a(More)
In this paper, we propose the concept of synthesizing a multimedia cooking recipe from a text recipe and a database composed of video clips depicting cooking operations. A multimedia cooking recipe is a cooking recipe where each cooking operation is associated with a corresponding video clip depicting it, aimed to facilitate the understanding of cooking(More)
The number of cooking recipe texts published on the Web is increasing in recent years. However, in general, cooking recipe texts have little flexibility. So, it is not always easy to retrieve cooking recipe texts that satisfy users' various demands. Therefore, it is necessary to create and offer recipes that suit the user's requirements. In this paper, we(More)
As part of ITS technology, to achieve quick map updates, we propose a method for automatically detecting changes in streetscapes from images captured by car-mounted omnidirectional cameras. It comprises two stages; accurate alignment of a map and street images taken at various times, and detection of changes in streetscapes from the aligned data. The system(More)
