专家您好，我按照8863.dvr_rdk_nsflink.patch.txt中的补丁对DVR修改并重新编译后,运行测试程序后发现加不加NF模块对于图像中已有的噪点没有什么影响，请问专家是我的噪点生成的问题还是其它什么原因，另外TI有没有NF模块起作用后前后画面对比的例子。以下为我的程序代码及运行结果。谢谢！
在CaptureLink_drv.c中CaptureLink_drvProcessData函数中模拟生成噪点的代码
for (frameId = 0; frameId < frameList.numFrames; frameId++)
{
pFrame = frameList.frames[frameId];
///if(pFrame->channelNum)
/// Vps_printf("capture ch%d\n", pFrame->channelNum);
CaptureLink_setFrameWallTime(pObj,pFrame);
queId = CaptureLink_getQueId(pFrame->channelNum);
queChId = CaptureLink_getQueChId(pFrame->channelNum);
///Vps_printf("queId=%d, queChId=%d\n", queId, queChId);
UTILS_assert(queId < CAPTURE_LINK_MAX_OUT_QUE);
UTILS_assert(queChId < CAPTURE_LINK_MAX_CH_PER_OUT_QUE);
CaptureLink_drvCheckAndSetFrameSkipMask(pObj, pFrame);
pObj->captureDequeuedFrameCount++;
pObj->captureFrameCount[queId][queChId]++;
if(pObj->captureFrameCount[queId][queChId]%20==0){ // add noise every 20 frames
for(i=0;i<20;i++){
*((unsigned *)pFrame->addr[0][0]+5000+i*1000+pObj->captureDequeuedFrameCount%3) = 0;
}
//Vps_printf("capture ch%d\n", pFrame->channelNum);
}
CaptureLink_drvRtResolutionUpdate(pObj, pFrame);
CaptureLink_drvBlindAreaProcessData(pObj,
queId,
queChId,
pFrame);
pFrame->perFrameCfg = NULL;
pFrame->channelNum = queChId;
sendMsgToTsk |= (1 << queId);
status = Utils_bufPutFullFrame(&pObj->bufQue[queId], pFrame);
UTILS_assert(status == FVID2_SOK);
}
