Ftl-CoV19: A Transfer Learning Approach to Detect COVID-19

Algorithm 1

Native convolutional layer (square image and filter).

	Input: Input image Img, Filter Filter, Filter Size fs, Max Filter Count nc, Filter stride s, Padding p
	Output: Filter map of corresponding size
(1)	filter_map ← Generate empty filter map with corresponding size by formula below
(2)	for each row in output.rows:
(3)	for each col in output.columns:
(4)	sub patch = image[(rows): (rows + fs − 1), (cols): (cols + fs − 1)]
(5)	filter map[row][col] = sub_patch  Filter
(6)	end for
(7)	end for
(8)	Return filter_map
	Here, represents Convolution Operation
