arith:
tests arithmetic encoding and decoding using somewhat random data.
overly verbose.
arith_encode:
tests arithmetic encoding by encoding test_file into test_file_arith.out
Not useful.
arith_decode:
doesn't compile
arith_fixup_shift:
Checks the correctness of schro_table_arith_shift[].
arith_speed:
measures the speed of the arithmetic decoder. First column is number
of decode bits tested. Second is fraction of 1 bits (on a scale of
0 to 256). Third is number of cycles to decode N bits averaged over
10 runs. Fourth is standard deviation of the mean of the 3rd column.
Ignore the last.
bits:
Prints out the bit representation of numbers encoded using
schro_bits_encode_uint() and schro_bits_encode_sint().
bits2:
Encodes/decodes arrays of random numbers using schro_bits.
encode:
encodes a ten frame segment (of solid grey data) for every size from
64x64 to 79x79.
global_motion:
checks schro_motion_field_global_prediction(), i.e., calculating
global motion from an array of motion vectors.
motion:
measures speed of schro_frame_copy_with_motion(), using all zero
vectors.
obmc:
calculates and displays OBMC arrays for a hard-coded obmc size.
phasecorrelation:
a toy to play with phase correlation for image detection.
predict:
broken
quant:
prints out a graph visualising the quantiser dead zone.
struct_offsets:
a tool to print out struct offsets for the arith assembly code
tables:
a tool to print out schrotables.c
wavelet:
tests 1-d wavelet transforms. I'm not sure if this code is correct.
wavelet_2d:
tests 2-d wavelet transforms. This code has been verified in multiple
ways that it is correct. (Or very consistently incorrect.)
