# Fine-grained Image Hashing on CUB200 2011 (test) Source: [Fine-grained Image Hashing on CUB200 2011 (test)]() Collection index: [llms.txt]() Data updated: 2026-05-19T12:54:18.627Z Evaluation of Fine-grained Image Hashing performance on the test split of the CUB-200-2011 dataset, reporting collision probability. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Fine-grained Image Hashing | | Dataset (including any stated split) | CUB200 2011 (test) | | Metric | Collision Probability | | Unit | SCALAR | | Direction | Lower is better | | Results loaded | 30 of 30 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [Collision Probability](): Lower is better; unit: SCALAR. ## Recorded results | Method | Collision Probability | Result date | Report paper | | --- | --- | --- | --- | | CS3H | 0.000002 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | CS3H | 0.000005 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | CS3H | 0.000019 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | CS3H | 0.000022 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | CS3H | 0.000068 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | CS3H | 0.000081 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | CS3H | 0.000209 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | CS3H | 0.000298 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | SDC | 0.00074 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | SPQ | 0.00075 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | MeCoQ | 0.00081 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | SPQ | 0.00086 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | CS3H | 0.000874 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | MeCoQ | 0.00089 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | CS3H | 0.001023 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | SDC | 0.00109 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | SPQ | 0.00124 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | SPQ | 0.004 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | SPQ | 0.01168 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | SPQ | 0.01347 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | SPQ | 0.01354 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | SPQ | 0.01359 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | SDC | 0.0143 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | MeCoQ | 0.0171 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | SDC | 0.01744 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | MeCoQ | 0.01804 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | SDC | 0.01806 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | SPQ | 0.01863 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | MeCoQ | 0.01912 | Not recorded | 6a0bef0ddbc836b87d82ca0f | | SPQ | 0.02053 | Not recorded | 6a0bef0ddbc836b87d82ca0f | ### CS3H Collision Probability: 0.000002.
