| dc.description.abstract | Leukemia,	simply	called	“Blood	cancer”	is	a	fatal	disease	where	the	white	blood	cells	(WBC)	increases	in	bone	marrow	and	peripheral	blood.		Acute	lymphoblastic	leukemia	(ALL)	is	one	of	the	most	common	types	of	leukemia	aroused	by	accumulation	and	overproduction	of	immature	and	cancerous	cells	known	as	lymphoblasts.	Presently,	the	diagnosis	of	ALL	includes	performing	a	full	blood	count,	blood	picture,	bone	marrow	biopsy,	cytochemical	stain,	immunophenotyping	and	cytogenetics.	These	techniques	are	highly	tedious,	costly,	requires	expertise	of	hematologists	and	available	only	in	few	hospitals.	Therefore,	as	an	alternative,	use	of	image	processing	to	diagnose	ALL	would	become	an	effective	solution.	Although,	several	research	groups	have	employed	image	processing	to	identify	ALL,	recognition	and	splitting	of	overlapping	red	blood	cells	(RBC)	with	WBC	has	yet	been	a	challenging	issue.	This	paper	is	about	an	application	which	includes	an	image	processing	algorithm	to	diagnose	ALL	while	attempting	to	solve	the	above	mentioned	issue	of	overlapping	cells.	The	algorithm	is	also	extended	to	detect	the	quality	devastation	in	blood	films	in	terms	of	storing	them	for	prolonged	period.	The	inputs	for	this	application	are	microscopic	peripheral	blood	images	of	ALL	patients	obtained	from	Department	of	Pathology	Clinic	at	Faculty	of	Medicine,	University	of	Colombo.	Then,	image	processing	techniques;	image	enhancement,	segmentation,	feature	extraction	and	classification	are	performed.	For	the	detection	and	diagnosis	of	leukemia,	segmentation	using	morphological	operations	in	OpenCV	Python	and	classification	using	KNearest	Neighbour	and	Support	vector	machine	implementations	has	been	proposed	in	this	research.	It	is	observed	that	the	proposed	algorithm	has	led	to	a	high	accuracy	in	diagnosing	ALL.	The	system	also	includes	a	PHP	based	web	application	that	serves	hematologists,	doctors	and	patients	to	log	in	to	their	specific	user	accounts	and	make	records,	insert	details	and	view	diagnosing	reports. | en_US |
