  1. 1. Image Analysis on Wood Fiber Cross-Section Images

    Master-uppsats, Institutionen för informationsteknologi

    Författare :Sitao Feng; [2011]
    Nyckelord :;

    Sammanfattning : Lignification of wood fibers has a significant impact on wood properties. To measure the distribution of lignin in compression wood fiber cross-section images, a crisp segmentation method had been developed. It segments the lumen, the normally lignified cell wall and the highly lignified cell wall of each fiber. LÄS MER

  3. 2. Evaluation of Red Colour Segmentation Algorithms in Traffic Signs Detection

    Master-uppsats, Datateknik
