I'd like to get cumulative mean value from a multiband image (4 bands). How can I do it in Arcgis, ERDAS and ENVI?

Thanks in advance

Cell Statistics in ArcGIS will calculate the mean (or statistic of choice) among multiple rasters on a cell-by-call basis.

Not sure what you mean by 'cumulative mean.' Perhaps you might be meaning the sum of the mean for each raster? If so, try the Get Raster Properties tool for each band and then sum them up as constants in Raster Calculator or Cell Statistics, making sure to set the Raster Analysis Properties and Extent in the Environments to same as your original rasters.
