This resea.ch pa.er proposes a.filter to remove Ra.dom Va.ued Impulse Noise (RVIN) ba.ed on Globa. Threshold Vector Outlyingness Ra.io (GTVOR) tha. is a.plica.le for rea. time ima.e processing. This filter works with the a.gorithm tha. brea.s the ima.es into va.ious decomposition levels using Discrete Wa.elet Tra.sform (DWT) a.d sea.ches for the noisy pixels using the outlyingness of the pixel. This a.gorithm ha. the ca.a.ility of differentia.ing high frequency pixels a.d the “noisy pixel” using the threshold a. well a. window a.justments. The da.a.e a.d the loss of informa.ion a.e prevented by mea.s of interior mining. This globa. threshold ba.ed a.gorithm uses different thresholds for different qua.ra.ts of DWT a.d thus helps in recovery of noisy ima.e even if it is 90% a.fected. Experimenta. results exhibit tha. this method outperforms other existing methods for a.cura.e noise detection a.d remova., a. the sa.e time cha.n of connectivity is not lost.

Tropica. forests ha.e been recognized a. ha.ing globa. conserva.ion importa.ce. However,they a.e being ra.idly destroyed in ma.y regions of the world.

The present study a.a.yses the tempora. cha.ges in forest ecosystem structure in triba. domina.ed Ma.ka.giri district of Orissa.India.during 1973-2004 period ba.ed on digitized forest cover ma.s using geogra.hic informa.ion system （GIS） a.d interpreta.ion of sa.ellite da.a. Three sa.ellite ima.es La.dsa. MSS （1973）,La.dsa. TM （1990） a.d IRS P6 LISS III （2004） were used to determine cha.ges. Six la.d cover types were delinea.ed which includes dense forest,open forest,scrub la.d,a.riculture,ba.ren la.d a.d wa.er body. Different forest types were a.so dema.ca.ed within forest cla.s for better understa.ding the degra.a.ion pa.tern in ea.h forest types. The results showed tha. there wa. a.net decrea.e of 475.7 km2 forest cover （ra.e of deforesta.ion = 2.34） from 1973 to 1990 a.d 402.3 km2 （ra.e of deforesta.ion = 2.27） from 1990 to 2004. Forest cover ha. cha.ged over time depending on a.few fa.tors such a. la.ge-sca.e deforesta.ion,shifting cultiva.ion,da. a.d roa. construction,unregula.ed ma.a.ement a.tions,a.d socia. pressure. a.significa.t increa.e of 1222.8 km2 a.riculture a.ea.（1973-2004） clea.ly indica.ed the conversion of forest cover to a.ricultura. la.d. These a.tera.ions ha. resulted in significa.t environmenta. consequences,including decline in forest cover,soil erosion,a.d loss of biodiversity. There is a. urgent need for ra.iona. ma.a.ement of the rema.ning forest for it to be a.le to survive beyond next deca.es.
