A Contour Approach to Thinning Algorithms

open access: yesCommunications, 2009
Thinning algorithms are widely used in many image processing tasks. Many thinning algorithms were proposed but they usually tend to process all image pixels in every iteration. Two approaches to contour thinning are described and a short discussion about

Development of the Norway spruce (Picea abies /L./ Karst.) stand established by various spacings and affected by abiotic harmful factors and ungulate game

open access: yesJournal of Forest Science, 2020
The paper presents the results of 30-year research on silviculture-production relationships in a 50-years-old Norway spruce stand (a small-pole stage) originated from artificial regeneration in a mountain forest.

Innovative productivity improvements in forest operations: a comparative study of the Assortment Grapple using a machine simulator

open access: yesJournal of Forest Science, 2020
Because of generally small log piles, loading forwarders during thinning is time consuming. The Assortment Grapple, an innovative grapple with an extra pair of claws which facilitates the handling of two assortments during one loading crane cycle, has ...

Regulating yield and wine quality of minimal prunning systems through the application of gibberellic acid

open access: yesOENO One, 2006
The use of gibberellic acid to increase berry size and to loosen up bunches in the production of seedless table grape varieties has a long history. The use of gibberellic acid on wine grapes, however, is very limited, mainly because some varieties can ...

Common walnut (Juglans regia L.) wood characteristics in two Italian plantations

open access: yesAnnals of Silvicultural Research, 2019
The Woodnat project (H2020) has the goal of identifying the problems that led to poor yields in walnut plantations established under the financial support of EU 2080/92 Regulation and Rural Development Programme, and of improving the market demand for ...

Selecting site characteristics at different spatial and thematic scales for shrubby cinquefoil (Potentilla fruticosa L.) distribution mapping

open access: yesMetsanduslikud Uurimused, 2016
The largest natural population of shrubby cinquefoil (Potentilla fruticosa) in the Baltic States was observed in the field to reveal the scale-dependent explanatory value of site characteristics for subsequent spatial distribution modelling of the ...
