Abstract
A method of processing a histogram generated by a time-of-flight (ToF) imager includes: filtering the histogram using a zero-crossing filter (ZCF) to generate a ZCF output signal; finding zero-crossing points in the ZCF output signal, where the zero-crossing points define one or more pulse regions in the ZCF output signal; computing, for each pulse region of the one or more pulse regions, a weighted sum of the pulse region; finding, in each pulse region, a maximum peak; classifying the maximum peak in each pulse region as a first type of peak or a second type of peak based on the weighted sum of the pulse region; and generating a list of ZCF targets from the maximum peaks classified as the first type of peaks.
