Find member by name.

Constructs a FloatingPoint from a raw floating-point number. On an Intel CPU, passing a non-normalized NAN (Not a Number) around may change its bits,

Frees a memory block (concept Allocator)

FullMatch(str, re) returns true iff regular expression re matches the entire str. PartialMatch(str, re) returns true iff regular expression re matches

returns a feature descriptor by feature index

returns the number of descriptors

Returns pointer to FV, if return 0 then FV not created */

GetInputPatchSize: returns the required size of the patch that the descriptor is built from (2 time larger than the patch after warping)

GetObjectFeatureCount: returns the number of object features

GetPCAFilename: get default PCA filename

GetPatchSize: returns the size of each image patch after warping (2 times smaller than the input patch)

returns the number of poses for each descriptor

returns the number of pyramid levels

Get the capacity of stack in bytes.

return 0 if trajectory is normal return >0 if trajectory abnormal */

Get the length of string. ! Since rapidjson permits "\u0000" in the json string, strlen(v.GetString()) may not equal to v.GetStringLength(). */
