The invention relates to crosstalk rejection convolution peaking. A method of processing a histogram generated by a time-of-flight (ToF) imager, the method comprising: filtering the histogram using a zero-crossing filter (ZCF) to generate a ZCF output signal; finding a zero crossing point in the ZCF output signal, wherein the zero crossing point defines one or more pulse regions in the ZCF output signal; for each of the one or more pulse regions, calculating a weighted sum of the pulse regions; searching a maximum peak value in each pulse region; classifying the maximum peak value in each pulse region as a first type peak value or a second type peak value based on the weighted sum of the pulse regions; and generating a list of ZCF targets from the maximum peaks classified as the first type of peaks. 本公开涉及串扰拒绝卷积峰值寻找。一种处理由飞行时间(ToF)成像器生成的直方图的方法，该方法包括：使用过零滤波器(ZCF)对直方图进行滤波以生成ZCF输出信号；在ZCF输出信号中寻找过零点，其中该过零点限定ZCF输出信号中的一个或多个脉冲区域；对于一个或多个脉冲区域中的每个脉冲区域，计算脉冲区域的加权和；在每个脉冲区域中寻找最大峰值；基于脉冲区域的加权和将每个脉冲区域中的最大峰值分类为第一类型峰值或第二类型峰值；以及从被分
