## KLTStopSequentialMode()

## `void KLTStopSequentialMode(
KLT_TrackingContext tc);
`

KLTStopSequentialMode() must be called when it is desired to set `tc->sequentialMode` to `FALSE`. In addition to setting this value, the function frees the memory pointed to by the fields `tc->pyramid_last`, `tc->pyramid_last_gradx`, and `tc->pyramid_last_grady`. This memory is allocated when KLTTrackFeatures() is called with `tc->sequentialMode` to `TRUE`. Without calling the present function, KLTTrackFeatures() and KLTReplaceLostFeatures() will continue to use the old pyramids even though they are no longer valid.
