UBICID

Color Image Database 2016




The University of Beira Interior Color Image Database is composed by 5 original RGB images that were obtained from two sources: Three real scenes (rural and urban) from the University of Manchester hyperspectral image database [1], and two real urban scenes from the "Universidade da Beira Interior" and "Universidade de Coimbra" hyperspectral image database [2]. From these images two different dataset (UBICID-1 and UBICID-2) were generated and made available only for research purposes through this web page.


UBICID-1 (Version 1.0)

The Color Image Database, UBICID-1 version 1.0 is composed by the 5 RGB original images plus a set of 125 images that resulted from induced chromatic impairments using 5 different error magnitudes in 5 different random directions in the CIELAB color space. The details of the experiment can be found in following papers. If you use this database in your publications, please refer both the following papers:

    • The UBICID-1 is available for download (~129 MB) here.

    UBICID-2 (Version 2.0)

    The Color Image Database, UBICID-2 version 2.0 is composed by 2 RGB original images plus a set of 80 images that resulted from induced chromatic impairments using 4 different error magnitudes in 2 complementary directions in the CIELAB color space. The details of the experiment can be found in following paper. If you use this database in your publications, please refer the following paper:

    • The UBICID-2 is temporarily unavailable.
