Public Functions

explicit RandomPosterize(const std::vector<uint8_t> &bit_range = {4, 8})

Constructor.

Parameters

bit_range – [in] Range of random posterize to compress image. uint8_t vector representing the minimum and maximum bit in range of [1,8] (Default={4, 8}).

样例

/* Define operations */
auto decode_op = vision::Decode();
auto random_op = vision::RandomPosterize({4, 8});

/* dataset is an instance of Dataset object */
dataset = dataset->Map({decode_op, random_op},  // operations
                       {"image"});              // input columns

~RandomPosterize() = default: Destructor.
