- srcImagePath String
-
The filepath of the source image.
- findImagePath String
-
The filepath of the image to find inside srcImagePath image.
- similarity Single

similarity:=80.5F) ' 80,5% similarity threeshold.
For Each match As TemplateMatch In matches

sb.AppendLine()
sb.AppendFormat("Similarity Image Percentage: {0}%", (match.Similarity * 100.0F).ToString("00.00"))
