the aim of the present study was to examine the effect of different types of imagery on the skills performance of 7-10-year-old soccer players. 45 children (mean age 8.44±1.13 year) with similar imagery abilitywere selected and randomly assigned to three groups (each group 15 subjects). the training protocol was performed three sessions a week for 6 weeks. data analysis indicated a significant ...

For improved multispectral classification and retrieval of Lambertian reflectances from patches of arbitrary surface orientation, we investigate the consequences of a dichromatic illumination model accounting for direct sunlight and diffuse skylight. This illumination model leads to the concept of spectral classes as two dimensional planes in the feature space. This paper addresses three questi...

An automatic process for relative registering and merging the panchromatic and multispectral images of SPOT5 is presented. The automated hierarchical local registration process makes use of feature information to select tie points from both images. The tie points are then used to refine the sensor model of the multispectral image by method of least squares solution. Both panchromatic and multis...
