Equivalent of Matlab filter2(filter, image, 'valid') in python -


i want know equivalent of matlab's filter2(filter, image, 'valid') function in python opencv or scikit-image library. concerned valid argument allows calculate convolution of filter , image without 0 padding image. aware of fact similar question posted on forum equivalent of filter2 function valid argument has not been described properly.

the documentation filter2 says filter2(h, x, shape) equivalent conv2(x,rot90(h,2),shape);

a python equivalent conv2 signal.convolve2d. equivalent you're looking is:

signal.convolve2d(x, np.rot90(h), mode='valid')

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
