Segmap

class mpdaf.sdetect.Segmap(file_or_image, cut_header_after='D001VER')

Bases: object

Handle segmentation maps, where pixel values are sources ids.

Methods Summary

align_with_image(other[, inplace, truncate, ...])	Rotate and truncate the segmap to match 'other'.
cmap([background_color])	matplotlib colormap with random colors.
copy()
get_mask(value[, dtype, dilate, inverse, ...])
get_source_mask(iden, center, size[, ...])
