Summary:A computer-implemented method to identify RPI (Radio Frequency Interference) in a spectrogram includes dividing, by a matrix module of a computer processor, the spectrogram into a plurality of blocks, each block comprising a matrix of data points. The method includes applying, by a masking module of the computer processor, a plurality of matrix pooling functions to each block, the plurality of matrix pooling functions configured to produce a plurality of summarized pools. The method includes creating, by a masking module of the computer processor, a line mask for each of the pools and creating, by the masking module, an RPI mask based at least on the line masks, the RPI mask being indicative of RPI.
