How can I soften just the edges of this image

Question

I am using python and opencv to cut an image using a mask. The mask itself is quite jagged and so the resulting image becomes a bit jagged around the edges like below

These are some effects you can do with the PIL image library:

from PIL import Image, ImageFilter
im_1 = Image.open("/constr/pics1/russian_doll.png") 
im_2 = im_1.filter(ImageFilter.BLUR) 
im_3 = im_1.filter(ImageFilter.CONTOUR) 
im_4 = im_1.filter(ImageFilter.DETAIL) 
im_5 = im_1.filter(ImageFilter.EDGE_ENHANCE) 
im_6 = im_1.filter(ImageFilter.EDGE_ENHANCE_MORE) 
im_7 = im_1.filter(ImageFilter.EMBOSS) 
im_8 = im_1.filter(ImageFilter.FIND_EDGES) 
im_9 = im_1.filter(ImageFilter.SMOOTH) 
im_10 = im_1.filter(ImageFilter.SMOOTH_MORE) 
im_11 = im_1.filter(ImageFilter.SHARPEN)

# now save the images

im_2.save("/constr/picsx/russian_dol_BLUR.png") 
im_3.save("/constr/picsx/russian_doll_CONTOUR.png") 
im_4.save("/constr/picsx/russian_doll_DETAIL.png") 
im_5.save("/constr/picsx/russian_doll_EDGE_ENHANCE.png") 
im_6.save("/constr/picsx/russian_doll_EDGE_ENHANCE_MORE.png") 
im_7.save("/constr/picsx/russian_doll_EMBOSS.png") 
im_8.save("/constr/picsx/russian_doll_FIND_EDGES.png") 
im_9.save("/constr/picsx/russian_doll_SMOOTH.png") 
im_10.save("/constr/picsx/russian_doll_SMOOTH_MORE.png") 
im_11.save("/constr/picsx/russian_doll_SHARPEN.png")
