Question: DBSCAN ( DB , eps, minPts ) { C : = 0 for each point P in Sequence DB { / * Cluster counter *

DBSCAN(DB, eps, minPts){
C :=0
for each point P in Sequence DB {
/* Cluster counter */
if label(P)!= undefined then continue
Neighbors N := RangeQuery(DB, P, eps)
if |N|< minPts then {
label(P) := Noise
continue
}
/* Already processed */
/* Find neighbors */
/* Density check */
/* Label as Noise */
C := C +1
label(P) := C
Stack S.push{N}
while not S.empty(){
Q = S.pop()
if label(Q)= Noise then label(Q) := C
if label(Q)!= undefined then continue
label(Q) := C
/* next cluster label */
/* Label initial point */
/* Neighbors to expand */
/* Process point Q */
/* Noise becomes border pt */
/* Previously processed */
/* Label neighbor */
Neighbors N := RangeQuery(DB, Q, eps)/* Find neighbors */
if |N|>= minPts then {/* Density check */
S.push{N}/* Add neighbors to stack */
}
}
}
}
