<i>Seam carving</i> is a content-aware image resizing method [Shamir and Avidan 2007], which assigns Sobel-operator-based energy to each pixel and describes seams as the eight-connected paths of pixels. Successive removal of the optimal seams, i.e., those seams with the lowest sum of energy, allows reduction in image size. Pixels with lower energy are(More)
Nardonaphthalenones A and B (1-2), one new apo-α-carotenone (3) and four new monoterpenoids (4, 8-9 and 11), along with six known compounds (5-7, 10, 12-13) were isolated from the dried roots and rhizomes of Nardostachys chinensis Batal. Their structures were elucidated by analysis of the spectroscopic data including NMR, HRESIMS and circular dichroism(More)
