The image sequences in this directory are CIPR ITU601 sequences. Images in the yuv directory are in YUV format, and images in the ras directory are in Sun Rasterfile format. +-----------+ + YUV + +-----------+ Images in YUV format is planed-oriented, with all data for Y channel comes first, followed by U and V data. ==========+============+=============+========================================== Sequence Frames Resolution Remark ==========+============+=============+========================================== mobile color 94 720x576 ITU 601/PAL Interlaced, first field starts on first line 4:2:2, 50 fields/sec ----------+------------+-------------+------------------------------------------ +-----------+ + Ras + +-----------+ ==========+============+=============+========================================== Sequence Frames Resolution Remark ==========+============+=============+========================================== football gray 60 720x486 color 97 720x486 ----------+------------+-------------+------------------------------------------ garden gray 99 720x486 color map used [1] ----------+------------+-------------+------------------------------------------ susie [2] gray 150 720x480 color map used [1] color 150 720x480 ----------+------------+-------------+------------------------------------------ tennis gray 40 720x486 color map used [1] ----------+------------+-------------+------------------------------------------ mobile gray 40 720x576 8bpp color 40 720x576 24bpp ----------+------------+-------------+------------------------------------------ [1] For gray scale images with color map, there are 768 color-map bytes appended to the end of each image. [2] The susie sequence in this direcotry was provided by Dr. Pierre Moulin at Bellcore, NJ. The original data was in the CCIR 601 format, 720x486, 30 frames/sec, 4:2:2 color subsampling (horizontal subsampling by factor of 2) of Y-Cr-Cb. This was converted to Sun Rasterfile format using the following transformation: [R] [1.0 1.4017 -0.0009] [Y] [G] = [1.0 -0.7142 -0.3437] [Cr-128] [B] [1.0 0.0010 1.7722] [Cb-128] which assumes an original transformation of: [Y] [ 0.299 0.587 0.114] [R] [Cr-128] = [ 0.500 -0.419 -0.081] [G] [Cb-128] [-0.169 -0.331 0.500] [B].
