Hint: Comparison of photos can take quite a long time and depends on how many photos you add and what settings you use. While receiving results saves loaded bitmaps and stores them in a cache in order to make the next bitmap loading of the same photos extremely fast. Page 8 of 28
Similar Photos : Advance settings You choose how to compare photos: Bitmaps method compares pixels of size-reduced images, Histograms method compares histograms. Small bitmap size increases comparison speed and reduces memory usage; large bitmap size gets more precise results. Blur Radius allows you to smooth edges on photos. Hint: Bitmap Size 48x48 is usually enough to get satisfactory comparison results. Using bigger bitmaps takes significantly more memory and it s not recommended for a large photo list. Hint: Align Colors preprocessing helps you find duplicate photos even after applying color adjustments such as contrast, brightness, white balance, auto levels, etc. Hint: Using Grayscale color mode significantly decreases comparison time.
