Effects of Image Compression on Automatic Count of Immunohistochemically Stained Nuclei in Digital Images

Table 1

Probability Values from Student's t-Tests Comparing Mean Counts in TIFF and JPEG Images of Different Compression Rates

Differences	TIFF vs. 3× JPEG	TIFF vs. 23× JPEG	TIFF vs. 46× JPEG
Globally	<0.001	<0.001	<0.001
No cluster/Low area cluster	0.002	0.059	0.125
Fewer than 100 nuclei	0.125	0.052	0.175
Large-area cluster	<0.001	<0.001	<0.001
More than 100 nuclei	<0.001	<0.001	<0.001

JPEG = joint photographic experts group; TIFF = tagged image file format.
