this study was conducted to determine water stress tolerance of two iranian dudaim melons (kerman & birjand) and one iranian muskmelon (samsoury). throughout the experiment, three different levels of irrigation with three irrigation starting points (-50, -65 and -75 cb of matric potential) were employed. results indicated that water stress significantly affected yield, firmness, fruit sugars as...

image denoising by block matching and threedimensionaltransform filtering (bm3d) is a two steps state-ofthe-art algorithm that uses the redundancy of similar blocks innoisy image for removing noise. similar blocks which can havesome overlap are found by a block matching method and groupedto make 3-d blocks for 3-d transform filtering. in this paper wepropose a new block grouping algorithm in th...
