The area in bright green is the vegetation that I'm trying to convert from raster to polygon (Value = 1 for green area, Value = 0 for no color area). I performed a simple unsupervised classification, reclassified into binary format based on a 1 = what I want, 0 = not what I want, then attempted to convert the resulting raster to polygon.
Below is the result I get in polygon format, which doesn't even come close to resembling the green area in the image above.

It is a little difficult to see from the screenshots you attached (next time just paste the original size, it will show small but allows access to the detailed image), but if yo uhave 0 and 1 values, both will be converted to polygons. If you are only interested in the 1's (vegetation) first use Set Null—Help | ArcGIS Desktop to set the 0 value to NoData.

Yo may also want to read this help topic to generalize the data before converting to polygons: Generalizing zones with Nibble, Shrink, and Expand—Help | ArcGIS Desktop
RasterToPolygon only uses the first band from a multiband raster. It looks like you have a 3 band raster.
This worked like a charm. Thanks Xander!
Glad it worked!
