What Constitutes Food Similarity? Visual Representations and Retrieval in Indian Cuisine

The study investigates how different visual representations affect the perception of food similarity in Indian cuisine. Using an expanded Khana dataset and seven pretrained models, the authors analyze image‑to‑image retrieval and image‑to‑dish neighborhoods, revealing that visual similarity can cross culinary-family boundaries and varies significantly across representations. Aggregated dish‑level similarities show some common structure, but this does not align strongly with recipe‑derived similarity, indicating that food similarity is not a fixed property but depends on representation, modality, and abstraction level.

CulturalMenuBench: Probing the Knowledge-Application Gap in Multimodal Culinary Reasoning

CulturalMenuBench is a new benchmark comprising 4,870 culinary items in 10 languages across 18 regions, designed to test multimodal language models on tasks that combine dish recognition, step-by-step cooking images, ingredients, procedural text, and regional labels. The benchmark reveals a large knowledge‑application gap: models that score over 94% on standard multiple‑choice questions fall to at most 56% when attributing dishes to Chinese regional cuisines, indicating that cultural knowledge is present but not activated by visual input. Diagnostic analyses show that accuracy is driven by visual distinctiveness rather than cultural structure, and that removing sequential cooking images selectively harms process‑grounded tasks, confirming the need for procedural evidence.

RFHNet: Relational and Frequency-Aware Hashing Network for Large-Scale Fine-Grained Food Image Retrieval

Fine-grained food image retrieval is a key task in computational gastronomy, with applications in food traceability, dietary monitoring, and smart catering systems. Although hashing-based retrieval is attractive for large-scale search due to its storage efficiency and fast Hamming-distance computation, existing methods often perform poorly in fine-grained food scenarios, where subtle local semantics and frequency-sensitive visual cues are essential.

OliveGemma: A 3 Billion Visual Language Model for Recognising the Mediterranean & European Diet

arXiv:2608. 03428v1 Announce Type: cross Abstract: Image based dietary assessment offers a scalable alternative to self reported food diaries, yet fine-grained food recognition remains challenging due to high intra-class variability and visually similar dishes.

NutriVision: Ingredient-Conditioned Fusion and Prediction for Single-Image Food Nutrition Estimation

NutriVision is an end‑to‑end framework that estimates calories, mass, fat, carbohydrates, and protein from a single RGB image and optional ingredient list. It generates depth information with DepthAnything‑V3, encodes ingredient descriptions via CLIP, and fuses visual geometry and ingredient semantics through an Ingredient‑Conditioned Frequency‑Aligned Fusion Module, an Ingredient‑Aware Mask‑based Prediction Head, and modality‑specific Internal Semantic Modeling blocks. On the Nutrition5k dataset, NutriVision achieves a mean PMAE of 13.60 ± 0.10 %, outperforming prior methods by significant margins.

ConstraintMatch: Compositional Image-Text Matching through Constrained Regional Evidence Selection

ConstraintMatch is a training‑free inference technique that improves image‑text matching by enforcing entity‑level regional consistency. It compares independent crop selections for each category and attribute against a shared crop choice within each entity, using the resulting gap as a matching cost. The method calibrates spatial references, clips per‑entity residuals, and subtracts a scaled mean cost from global similarity, achieving significant gains over global matching and SGI across multiple benchmarks.

CRISP: Compositional Relations as Invariant Structural Priors for Domain Generalization

CRISP (Compositional Relational Invariance from Spatial Primitives) is an image‑classification framework that decomposes visual recognition into primitive elements and their relational composition. It represents these compositions with soft unary, binary, and ternary predicates over primitive locations and appearance, enabling differentiable spatial and visual alignment learned end‑to‑end. Evaluated on five DomainBed datasets covering style, provenance, and camera‑trap shifts, CRISP achieves new state‑of‑the‑art performance on both benchmarks.
